Abstract:
We present the second release of the Meta-Catalogue of X-ray detected
Clusters of galaxies (hereafter MCXC-II). The MCXC-II has been
compiled from publicly available ROSAT All Sky Survey-based (NORAS,
REFLEX, BCS, SGP, NEP, MACS, CIZA, RXGCC) and serendipitous (160SD,
400SD, SHARC, WARPS, and EMSS) cluster catalogues. Redshifts were
systematically checked and updated if necessary, and additional
redshift information (type and origin) added. The X-ray data were
standardised to an overdensity of 500 using a new procedure based on
the use of the original flux and aperture measurements available in
the input catalogues. MCXC-II contains 2221 entries, essentially
completing the census of ROSAT cluster detections by including objects
from the REFLEX-II and RXGCC surveys, in addition to providing a
complete and fully-homogenised sub-catalogue of all published MACS
clusters. Duplicate entries from overlaps between the survey areas of
the individual input catalogues were carefully handled. For each
cluster the MCXC-II provides three identifiers, a redshift,
coordinates, membership in the original catalogue, and standardised
[0.1-2.4]keV band luminosity L500, total mass M500, and radius R500.
Uncertainties on L500 were computed from the flux errors in the
original catalogues. MCXC-II additionally furnishes information on
overlaps between the input catalogues, gives the luminosity and its
uncertainty when measurements from different surveys are available,
and provides notes on individual objects.
Description:
MCXC-II was constructed from publicly available RASS-based (NORAS,
REFLEX, BCS, SGP, NEP, MACS, CIZA, and RXGCC) and serendipitous
(160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues (see Sect.
2). Clusters with newly available redshifts from the NORAS, SGP,
WARPS, and 160SD surveys were included (47 systems), in addition to
new objects from the REFLEX II, MACS, and RXGCC catalogues (439
systems). MCXC-II additionally contains a complete sub-catalogue of
all published MACS objects (Sect. 2.4.2). Duplicates and overlaps were
exhaustively identified, leading to a final total entry count of 2221
objects.

Note (1): z type as follows:
S = spectroscopic
P = photometric
SP = a combination of photometric and spectroscopic values
E = estimated
u = unknown
Note (2): z flag as follows:
Catalogue = original value from catalogue.
New = No redshift was available in the source catalogue;
the new redshift origin is given in r_z
Revised = redshift in the catalog has been updated
Consolidated = the source of the redshift in the catalogue and/or its type was
unclear. We propose another reference (given in r_z), with the
corresponding redshift for consistency. The difference with
the catalogue value is negligible.
Note (3): Method to convert aperture luminosity to L500 as follows:
ITER = by iteration
SC = using a fixed size correction
Note (4): Collated notes from original input source catalogues. In some cases,
these have been expanded from the original abbreviated form, or combined
from different tables in the input catalogue paper.
Note (5): Individual formatted notes on the cluster
(Code | Section | Description).
The category 'Code' covers eight different cases:
PLc = Point-Like contamination: cluster emission contaminated by
AGN (no AGN redshift available)
PLc_intra = Point-Like contamination intra: cluster emission contaminated
by AGN inside the cluster
PLc_extra = Point-Like contamination extra: cluster emission contaminated
by foreground/background AGN
complexStr = Complex X-ray structure: cluster with sub-structures and/or
close-by clusters on the plane of the sky
Dup = Duplicate: two different objects in MCXC-I identified as one
single object in MCXC-II
losStr = line-of-sight structure: structure on the line of sight
XOoff = Offset between the X-ray and Optical-counterparts as discussed
in the paper
Other = Any other useful information identified during the
construction of MCXC-II
