Description:
Paper XVII. X-ray and Sunyaev-Zel'dovich properties of the redshift 2.0
galaxy cluster XLSSC 122.
We present results from a 100ks XMM-Newton observation of galaxy
cluster XLSSC 122, the first massive cluster discovered through its
X-ray emission at z∼2. The data provide the first precise constraints
on the bulk thermodynamic properties of such a distant cluster, as
well as an X-ray spectroscopic confirmation of its redshift. We
measure an average temperature of kT=5.0±0.7keV; a metallicity with
respect to solar of Z/Z☉=0.33+0.190.17, consistent with
lower-redshift clusters; and a redshift of z=1.99+0.070.06,
consistent with the earlier photo-z estimate. The measured gas density
profile leads to a mass estimate at r500 of
M500=(6.3±1.5)1013M☉. From CARMA 30 GHz data, we measure the
spherically integrated Compton parameter within r500 to be
Y500=(3.6±0.4)10-12. We compare the measured properties of XLSSC
122 to lower-redshift cluster samples, and find good agreement when
assuming the simplest (self-similar) form for the evolution of cluster
scaling relations. While a single cluster provides limited
information, this result suggests that the evolution of the
intracluster medium in the most massive, well-developed clusters is
remarkably simple, even out to the highest redshifts where they have
been found. At the same time, our data rearm the previously reported
spatial oset between the centres of the X-ray and SZ signals for XLSSC
122, suggesting a disturbed configuration. Higher spatial resolution
data could thus provide greater insights into the internal dynamics of
this system.
list17.dat: FITS reduced images & spectra of XLSSC 122.
Paper XVIII. ATCA 2.1 GHz radio source catalogue.
atcacomp.dat: The table contains the component catalogue of all 6350
components detected with S/N≥5 in the full Australia Telescope
Compact Array 2.1 GHz continuum survey of the XXL-South field. The
observations covered the entirety of the 25 square degree XXL-South
field. The radio data has an angular resolution of 5.4 x 4.2 square
arcsec and a median rms of 41 uJy per beam. There are 1677 resolved
components.
atcasrc.dat: The table contains the source catalogue of all 6287
sources detected with S/N≥5. There are 1626 resolved sources, of
which 48 are multiple-component objects.
The tables contain various observed parameters of the radio sources,
such as position, peak flux density and signal-to-noise ratio.
Paper XX. The 365 cluster catalogue.
In the currently debated context of using clusters of galaxies as
cosmological probes, the need for well-defined cluster samples is
critical. The XXL Survey has been specifically designed to provide a
well characterised sample of some 500 X-ray detected clusters suitable
for cosmological studies. The main goal of present article is to make
public and describe the properties of the cluster catalogue in its
present state, as well as of associated catalogues of more specific
objects such as super-clusters and fossil groups. Following from the
publication of the hundred brightest XXL clusters, we now release a
sample containing 365 clusters in total, down to a flux of a few
10-15erg/cm2/s in the [0.5-2]keV band and in a 1' aperture. This
release contains the complete subset of clusters for which the
selection function is well determined plus all X-ray clusters which
are, to date, spectroscopically confirmed. In this paper, we give the
details of the follow-up observations and explain the procedure
adopted to validate the cluster spectroscopic redshifts. Considering
the whole XXL cluster sample, we have provided two types of selection,
both complete in a particular sense: one based on flux-morphology
criteria, and an alternative based on the [0.5-2]keV flux within one
arcmin of the cluster centre. We have also provided X-ray temperature
measurements for 80% of the clusters having a flux larger than
9x10-15erg/cm2/s.
xxl365gc.dat: We provide the list of spectroscopically confirmed C1
and C2 clusters of galaxies from the XXL-365-GC catalogue, i.e. tab. 5
of the article. It includes only clusters with a spectroscopic
validation. For these clusters, we provide (when available) a direct
determination of the X-ray gas mass within a 500kpc aperture, of the
r_500 radius (the radius of the sphere inside which the mean density
is 500 times the critical density of the Universe at the cluster's
redshift), of the temperature within 300kpc, of the X-ray luminosity
and uncertainty in the [0.5-2]keV rest-frame energy range and within
the r_500 radius, and the X-ray flux and uncertainty in the [0.5-2]
keV band and within a 60 arcsec radius.
NOTE: the formatting of Mgas500kpc, T300kpc and LXXL500MT (and
associated errors) in the original issue of this file was partially
inappropriate while XXL paper authors used the correctly formatted
values. In Mar 2019 we provide a revised version with the correct
formatting.
Paper XXII. The XXL-North spectrophotometric sample and galaxy stellar
mass function in X-ray detected groups and clusters
We have built a complete spectrophotometric sample of galaxies within
X-ray detected, optically spectroscopically confirmed groups and
clusters (G&C), covering a wide range of halo masses at z≤0.6 In the
context of the XXL survey, we analyse a sample of 164 G&C in the
XXL-North region (XXL-N), at z≤0.6, with a wide range of virial
masses (1.24x1013≤ M500(M☉_)≤6.63x1014) and X-ray
luminosities (2.27x1041≤LXXL500(erg/s)≤2.15x1044). The G&C
are X-ray selected and spectroscopically confirmed. We describe the
membership assignment and the spectroscopic completeness analysis,and
compute stellar masses. As a first scientific exploitation of the
sample, we study the dependence of the galaxy stellar mass function
(GSMF) on global environment. We present a spectrophotometric
characterisation of the G&C and their galaxies. The final sample
contains 132 G&C, 22111 field galaxies and 2225 G&C galaxies with
r-band magnitude <20. Of the G&C, 95% have at least three
spectroscopic members, and 70% at least ten. The shape of the GSMF
seems not to depend on environment (field versus G&C) or X-ray
luminosity ( used as a proxy for the virial mass of the system). These
results are confirmed by the study of the correlation between mean
stellar mass of G&C members and LXXL500.We release the
spectrophotometric catalogue of galaxies with all the quantities
computed in this work. As a first homogeneous census of galaxies
within X-ray spectroscopically confirmed G&C at these redshifts, this
sample will allow environmental studies of the evolution of galaxy
properties.
xxlngal.dat: The final catalogue contains all the properties described
in this paper for the subsample of galaxies with 0<z≤0.6, r≤20
and a derived stellar mass estimate. The released sample is composed
of 24336 galaxies, both in the field and in G&C, and the contribution
of the different surveys is the following: 95% of redshifts come from
GAMA (23178 galaxies out of 24336), 3% are from SDSS_DR10 (763
galaxies out of 24336) and the rest come from ESO Large Programme +
WHT XXL dedicated observational campaigns (0.5%, 115 galaxies out of
24336) and VIPERS (0.2%, 48 galaxies out of 24336). The catalogue
contains the astrometry from CFHTLS, the redshift, the name of the
parent catalogue/survey, the "origin flag" and "quality flag" that
were introduced in Sect. 2.3 of the paper, all the membership related
quantities, absolute magnitudes, stellar masses and completeness
values.
Paper XXVI. Optical and near infrared identifications of the ATCA 2.1GHz
radio sources in the XXL-S Field.
atca.ctpt.dat : This file report the optical, near infrared and X-ray
counterparts of the radio sources detected in the XXL-S Field. The
radio data have been obtained with the Australia Telescope Compact
Array (ATCA) at 2.1GHz with a resolution of 4.76 arcsec. The optical
data used have been obtained at the Cerro Tololo Inter-American
Observatory (CTIO) with the MOSAIC II imager during the Blanco
Cosmological Survey (BCS) in the g,r and i bands and with the Dark
Energy Camera (DECam) in the g,r,i and z bands. The infrared data have
been obtained in the J,H and K bands during the Vista Hemisphere
Survey (VHS), a public ESO large programme survey. The X-ray data have
been obtained with the XMM-Newton X-ray Telescope as part of the
XMM-Newton Extragalactic Survey. The Likelihood Ratio technique has
been used to associate the counterparts to the radio sources.
Paper XXVII. The 3XLSS point source catalogue.
We present the version of the point source catalogue of the XXL survey
that was used, in part, in the first series of XXL papers. In this
paper we release, in our database in Milan and at CDS: (i) the X-ray
source catalogue with 26056 objects in two areas of 25 deg2; (ii)
the associated multiwavelength catalogues with candidate counterparts
of the X-ray sources in the infrared, near-infrared, optical and
ultraviolet (plus spectroscopic redshift when available); and (iii) a
catalogue of spectroscopic redshifts recently obtained in the southern
XXL area. We present also the basic properties of the X-ray point
sources and their counterparts. Other catalogues described in the
second series of XXL papers will be released contextually, and will
constitute the second XXL data release.
3xlss.dat: We provide the source list for the full area (2x25 square
degrees) of both XXL fields (XXL-N and XXL-S), with a total of 26056
point-like or extended sources above a detection likelihood of 15 in
either 0.5-2 or 2-10 keV bands. The 3XLSS table at CDS contains the
main X-ray parameters, while further parameters and data products
(X-ray images and exposure maps) are available in the Milan XMM-LSS
database site. For multiwavelength data see associated tables
3XLSSOPTN and 3XLSSOPTS.
3xlsoptn.dat: We provide the multiwave counterpart list for the
northern area (XXL-N) of the XXL fields with a total of 14168 X-ray
sources with zero, one or more potential counterparts. Standardized AB
magnitudes are given for various bands from SDSS, CFHT, VISTA, UKIDSS,
WIRcam, IRAC, GALEX and WISE surveys. The preferred (primary)
counterpart has a rank from 0.0 to 1.0, while higher ranks are for
secondary counterparts.
In addition spectroscopic redshift and association with SIMBAD and NED
are given where available. Further parameters and data products (FITS
thumbnail images, SIMBAD and NED links) are available in the Milan
XMM-LSS database site. For X-ray data in both XXL-N and XXL-S areas
see associated table 3XLSS.
3xlsopts.dat: We provide the multiwave counterpart list for the
southern area (XXL-S) of the XXL fields with a total of 11888 X-ray
sources with zero, one or more potential counterparts. Standardized AB
magnitudes are given for various bands from BCS, DECam, VISTA, IRAC,
GALEX and WISE surveys. The preferred (primary) counterpart has a rank
from 0.0 to 1.0, while higher ranks are for secondary counterparts.
In addition spectroscopic redshift and association with SIMBAD and NED
are given where available. Further parameters and data products (FITS
thumbnail images, SIMBAD and NED links) are available in the Milan
XMM-LSS database site. For X-ray data in both XXL-N and XXL-S areas
see associated table 3XLSS.
xxlaaoz.dat: In the framework of the publication of the 3XLSS point
source catalogue, we provide also the redshifts obtained with the
AAOmega spectrograph in 2016 for 3572 sources in the XXL-S field,
supplementing those published in XXL Paper XIV (Lidman et al.,
2016PASA...33....1L 2016PASA...33....1L) and CDS IX/49/xxlaaoz).
The AAOmega spectrograph in conjunction with the two-degree field
(2dF) fibre positioner on the AAT was used to measure redshift of
sources in the XXL-S field during two campaigns in 2015 and 2016. The
2015 results were published in XXL Paper XIV (Lidman et al.,
2016PASA...33....1L 2016PASA...33....1L) and CDS IX/49/xxlaaoz), while the newer 2016
results for 3572 objects are published with the present paper.
xxlpoint.dat: The table (B.1 in Paper XXVII, Chiappetti et al.) is a
list of all XMM survey-type observations(≤AO-10) in the XXL fields,
providing the match between the internal naming and the ESA XXM
log,the coordinates and useful exposure times of the XMM pointings,
their quality and ancillary information. The initial columns of the
table are identical to the one published with XXL Paper I (Pierre et
al., 2016A&A...592A...1P 2016A&A...592A...1P and IX/49/xxlpoint). The astrometric offsets
used in XXL data releases DR1 and DR2 were added in this new version
of the table.

Paper XXIX. GMRT 610 MHz continuum observations.
xxl_gmrt.dat: The table presents a catalogue of 5434 sources detected
at ≥7 rms within the 25 square-degree GMRT-XXL-N 610MHz radio
continuum survey, conducted at 50cm wavelength with the Giant
Metrewave Radio Telescope (GMRT) towards the XXL Northern field
(XXL-N). We combined previously published observations of the
XMM-Large Scale Structure (XMM-LSS) field, located in the central part
of XXL-N, with newly conducted observations towards the remaining
XXL-N area, and imaged the combined data-set using the Source Peeling
and Atmospheric Modeling (SPAM) pipeline. The final mosaic encompasses
a total area of 30.4 square degrees, with rms<150uJy/beam over 60% of
the area. The rms achieved in the inner 9.6 square degree area,
enclosing the XMM-LSS field, is about 200uJy/beam, while that over the
outer 12.66 square degree area (which excludes the noisy edges) is
about 45uJy/beam. The resolution of the final mosaic is 6.5-arcsec.
More details about the catalog, including its verification, reliability,
and false detection rate can be found in the paper.

Paper XXXIV. Double irony in XXL-North.
Two prominent radio galaxies were identified in a visual examination
of the mosaic of XXL-North obtained with the Giant Metrewave Radio
Telescope at 610MHz. Counterparts were searched for in other bands.
Spectroscopic redshifts from the GAMA database were used to identify
clusters and/or groups of galaxies, estimate their masses with the
caustic method, and quantify anisotropies in the surrounding galaxy
distribution via a Fourier analysis. Both radio galaxies are of FRI
type and are hosted by early-type galaxies at a redshift of 0.138. The
first radio source, named the Exemplar, has a physical extent of about
400kpc; it is located in the cluster XLSSC112, which has a temperature
of about 2keV, a total mass of about 1014 solar masses, and resides
in an XXL supercluster with eight known members. The second source,
named the Double Irony, is a giant radio galaxy with a total length of
about 1.1Mpc. Its core coincides with a cataloged point-like X-ray
source, but no extended X-ray emission from a surrounding galaxy
cluster was detected. However, from the optical data we determined
that the host is the brightest galaxy in a group that is younger, less
virialized, and less massive than the Exemplar's cluster. A
friends-of-friends analysis showed that the Double Irony's group is a
member of the same supercluster as the Exemplar. There are indications
that the jets and plumes of the Double Irony have been deflected by
gas associated with the surrounding galaxy distribution. Another
overdensity of galaxies (the tenth) containing a radio galaxy was
found to be associated with the supercluster. Radio galaxies can be
used to find galaxy clusters/groups that are below the current
sensitivity of X-ray surveys.

Paper XXXVI. Evolution and black hole feedback of high-excitation and
low-excitation radio galaxies in XXL-S
atcaclas.dat: This file contains the core multiwavelength quantities
and flags used to classify the 1.4GHz radio sources cross-matched to
an optical counterpart in the XXL-S field. There are 4758 radio
sources with counterparts. The radio data have been obtained with the
Australia Telescope Compact Array (ATCA) at a central frequency of
2.1GHz with a resolution of 4.76-arcsec. The mid-infrared (MIR)
magnitude data have been obtained from the WISE all-sky survey and the
Spitzer-IRAC Spitzer South Pole Telescope Deep Field (SSDF). All other
optical/IR magnitudes are derived from SED fits. The optical spectra
data were obtained with the AAOmega spectrograph on the Australian
Astronomical Telescope.

Note (1): Note on Origin_Flag:
The different surveys are divided into three classes of priority.
The values assumed by the Origin_Flag are 1, 2, 3: the smaller the value the
higher the priority.
The list of the surveys with their attributed Origin_Flag is given below:
1) AATAAOmegaGAMA, ESOLargeProgramme, AAOmega2012, NTT, WHT,
XMMLSS, SDSS_DR10.
2) VIPERS/XXL, VVDS_UD, VVDS_deep.
3) Akiyama, Alpha_compilation, LDSS03, Milano, NED, SNLS, Simpson, Stalin,
Subaru, Magellan.
Note (2): Note on Quality_Flag:
The Quality_Flag can assume six values: 0, 1, 2, 3, 4, 400: from 0 to 4, the
higher the value the higher the precision and reliability of the redshift
estimate.
400 is the value assumed by the spectra with no multiplicity in the parent
database.
Note (3): Distances are given in units of r_200.
For field galaxies or only single membership the value is set to zero.
Note (4): Note on XLSSC_3r200:
In the case of multiple memberships, the multiple identification numbers
are separated using the underscore symbol (_).
Note (5):
Absolute magnitudes and stellar masses are computed using LePhare.
Note (6): Note on yMag:
The MegaCam filter i was broken during the survey and a new i band filter
was introduced (``y'').
Note (7): Note on ComplSM:
The value is computed using the subsample of the spectrophotometric
catalogue including only the galaxies with a reliable stellar mass estimate
by LePhare.

The numeric identifier is a number for single individual components.
It is an undescore-separated list of component identifiers for multiple
sources (see Paper Paper XXVIII, Butler et al.).
Note (2): For all magnitudes 99.0000 means undefined (not observed), while a
negative value corresponds to the limit magnitude in the band.
Magnitudes are 3" aperture magnitudes in the AB system.
Note (3): Note on Bflux and CDflux:
The flux is set to -1.0 when undefined for any reason (in particular
it is set to undefined for all C1 clusters)

Note (5): Note on Bcorerad andDcorerad:
The soft or hard band core radii can assume value -1 when the extended
source fit fails in the relevant band.
Note (6): Note on BRAdeg and CDRAdeg:
This note applies to all 0.5-2keV (2-10keV) band columns from BRAdeg
to f_Bflux (CDRAdeg to f_CDflux).
The coordinates and count rates, and associated position error and flux
in a band are relevant to the pointlike or extended fit according to the
classification of the source
Note (7): Note on e_Bpos and e_CDpos:
The position error is computed from the count rate and off axis angle
according to prescriptions given in the paper.
For extended sources it is set to 0.0
Note (8): Note on Bflux and CDflux:
The flux is set to -1.0 when undefined for any reason (in particular
it is set to undefined for all C1 clusters)
Note (9): Note on e_Bflux and e_CDflux:
The errors are set to -1.0 when undefined for any reason, and to blank
if a source was not detected in the band.
Note (10): Note on f_Bflux and f_CDflux:
The flux flag indicates how the fluxes computed from MOS or pn rates alone
differ from the mean flux, with the following coding:
0 = difference < 20%
1 = difference between 20 and 50%
2 = difference > 50%

Note (1): Note on FieldName:
XXLn or XXLs stand for the XXL-N (XXL-S) field;
a,b,c... tags indicate that the same a,b,c... tags indicate that the same
sky position has been observed several times in different AOs (consult the ESA
XMM log using the ESA ObsId) because the quality of earlier pointings was
insufficient; the z tag means that a fictitious pointing has been created
combining the events of all usable repeated pointings, in order to improve
the quality. In total there are 542 and 81 a,b,c and z pointings respectively.
In case of repeated fields, as well as of overlaps from adjacent fields, the
X-ray catalogue will remove overlapping detections, and consider only the one
from the better pointing, or, in case of equal quality, the object with the
smallest off-axis angle.
Note (2):
The exposure for the MOS and pn detectors is the remaining exposure (in ks)
after selection of the good-time intervals.
Note (3): Note on quality as follows:
0 = good quality
1 = low exposure
2 = high background
3 = 1&2
Note (4): Note on badfield:
0: best acceptable observation at a given position
1: for deep/good observation from the archives, not part of XXL proper
2: other acceptable XXL observation at same position
3: bad pointings i.e. quality=3
This flag is used in the overlap removal procedure
Note (5): Note on db:
This column is ticked if Xamin detected at least one object in this pointing.
Note (6): Note on cat:
This column is ticked if at least one source in this pointing survived the
overlap removal procedure and hence entered the X-ray source catalogue.
Note (7): Astrometric offsets computed by XMM SAS task ``eposcorr''
Note (8): Note on corrflag:
This column indicates the reference catalogue for astrometric correction
(one of CFHTLS, BCS or USNO) if it was applied, or none if it was not
applied (irrespective whether nominal offsets were computed or not).

All other magnitudes (absolute or apparent) are in the AB system and are
derived from the SED fit. Apparent DECam magnitudes are calculated from the
SED fit and luminosity distance.
Note (20): A value of -99 means unavailable (not observed or inapplicable). This
applies to zspec, W1mag, W2mag, W3mag, W4mag, IRAC1mag and IRAC2mag.
For other columns which have undefined values (e.g. most flags) they are
indicated with the usual CDS null/blank value.

3 = multiple weak spectral line matches or single strong spectral line match
4 = multiple strong spectral line matches
Note (22): Best fit MARZ spectral template as follows:
These are the possible best fit MARZ spectral templates:
Q = quasar
ETAG = early type absorption galaxy
LTEG = late type emission galaxy
HRSFG = high redshift star forming galaxy
CG = composite galaxy
ITG = intermediate type galaxy
TG = transitional galaxy
Note (23): Note on OIIRFlux, HbRFlux, OIIIRFlux, HaRFlux, NIIRFlux.
Fraction of the continuum flux at the corresponding wavelength.
Conventionally sign indicates:
Positive value = emission line
Negative value = absorption line
Note (24): Note on OIISNR, HbSNR, OIIISNR, HaSNR, NIISNR
Low SNR values for spectral lines do not necessarily indicate the presence
of a line, as the automated results from Robospect were checked only for
sources that had clear [OIII] lines and/or all four of the BPT lines
([OIII], H-beta, H-alpha, and [NII]).

Global notes:
Note (G1): Note on Xseq:
This note applies to all merged band columns from Xseq to XDEs.
Columns whose label begins with X refer to band-merged X-ray properties
and are always present for all records.
Note (G2): Note on Xcatname:
In a very few cases the IAU standard catalogue name has an a/b suffix
after the coordinate designation. This occurs when the band merging is
ambiguous and one 0.5-2keV band source may have two different hard band
counterparts, or viceversa.
Note (G3): Note on Bseq and CDseq:
This note applies to all 0.5-2keV (2-10keV) band columns from Bseq
to f_Bflux (CDseq to f_CDflux).
Columns whose label begins with B refers to X-ray properties in the
0.5-2keV band, and columns whose label begins with CD refers to
X-ray properties in the 2-10keV band.
If a source was not detected in the band, all these columns are blank.
For 3xlsoptn.dat and 3xlsopts.dat only:
(for the primary counterpart; they are unconditionally blank for secondary
counterparts i.e. Xrank ≥ 2.0).
Note (G4): Note on Bp1 and CDp1:
The P1 classification flag is set to 1 for bona-fide pure point sources.
Note (G10): Note on Xlsspointr:
A non-zero value contains the Xseq of the corresponding source in the
XMM-LSS 2XLSSd catalogue (Chiappetti et al., 2013MNRAS.429.1652C 2013MNRAS.429.1652C,
Cat. J/MNRAS/429/1652), a sub-area of XXL-N, zero otherwise.
Note (G11): Note on XLSSC:
The XLSSC cluster number for clusters in the XXL365GC sample
(Paper XX, Adami et al.), or 0 where not yet assigned (Table G.2 of
Paper XX, Adami et al.) or not confirmed reserved
for future analysis, or -1 where not applicable (pointlike sources)
Note (G12): Note on Xrank:
The identification rank can assume the following values:
0.0 = primary physically single counterpart within 10" from X-ray position
0.1 = primary logically single (all other counterparts were rejected)
0.2 = recovered counterpart (single but with bad estimators)
0.4 = "blank field" (no catalogued counterpart)
0.9 = primary counterpart much better than all secondaries (ranked 2.2)
1.0 = primary counterpart marginally better than one of the secondaries
2.1 = secondary counterpart marginally worse than rank 1.0 primary
2.2 = any other secondary counterpart
Note (G13): Note on CtpRAdeg:
The nominal counterpart coordinates refer to the counterpart coordinate
from the survey which is closest to the X-ray position. They are zero
for "blank fields" (Xrank=0.4)
Note (G14): Note on star as follows:
The star flag is non-zero if the counterpart is assumed a star because
1 = the spectroscopic redshift is zero
2 = visual inspection shows it to be a star
3 = both previous conditions are satisfied
Note (G15): Note on agn1000:
This flag is non-zero if source is listed in Paper VI (Fotopoulou et al.,
2016A&A...592A...5F 2016A&A...592A...5F) and namely is 1 if the counterpart of Paper VI
(Fotopoulou, et al., 2016A&A...592A...5F 2016A&A...592A...5F) is confirmed, and
-1 if the X-ray source was listed in Paper VI (Fotopoulou, et al.,
2016A&A...592A...5F 2016A&A...592A...5F) but counterpart has changed.
Note (G16):
This note applies to all entries related to photometric counterparts.
The set of columns relevant to a given survey is blank if not used.
If there is a counterpart in survey 'surv' there are columns named
RA'surv'deg, DE'surv'deg and 'surv'dist.
If there is a measurement in a given 'band', then there are columns
named 'surv'mag'band' and e_'surv'mag'band', otherwise they are blank.
