Abstract:
We release the next installment of the Stripe 82 X-ray survey
point-source catalog, which currently covers 31.3deg2 of the Sloan
Digital Sky Survey (SDSS) Stripe 82 Legacy field. In total, 6181
unique X-ray sources are significantly detected with XMM-Newton
(>5σ) and Chandra (>4.5σ). This catalog release includes
data from XMM-Newton cycle AO 13, which approximately doubled the
Stripe 82X survey area. The flux limits of the Stripe 82X survey are
8.7x10-16erg/s/cm2, 4.7x10-15erg/s/cm2, and 2.1x10-15erg/s/cm2
in the soft (0.5-2keV), hard (2-10keV), and full bands (0.5-10keV),
respectively, with approximate half-area survey flux limits of
5.4x10-15erg/s/cm2, 2.9x10-14erg/s/cm2, and 1.7x10-14erg/s/cm2.
We matched the X-ray source lists to available multi-wavelength
catalogs, including updated matches to the previous release of the
Stripe 82X survey; 88% of the sample is matched to a multi-wavelength
counterpart. Due to the wide area of Stripe 82X and rich ancillary
multi-wavelength data, including coadded SDSS photometry, mid-infrared
WISE coverage, near-infrared coverage from UKIDSS and VISTA Hemisphere
Survey, ultraviolet coverage from GALEX, radio coverage from FIRST,
and far-infrared coverage from Herschel, as well as existing ∼30%
optical spectroscopic completeness, we are beginning to uncover rare
objects, such as obscured high-luminosity active galactic nuclei at
high-redshift. The Stripe 82X point source catalog is a valuable data
set for constraining how this population grows and evolves, as well as
for studying how they interact with the galaxies in which they live.
Description:
XMM-Newton and Chandra X-ray sources matched to the SDSS, WISE,
UKIDSS, VHS, and GALEX catalogs using the maximum likelihood estimator
(MLE). X-ray sources are matched to FIRST and Herschel sources using a
nearest neighbor matching. Spectroscopic redshifts obtained from
dedicated ground-based follow-up are also published in this catalog.
The archival Chandra and archival and AO10 XMM-Newton catalogs
supersede those from the previous catalog release in 2013.

--------------------------------------------------------------------------------
Note (1): Flag to indicate if source is extended as follows:
0 = point-like in all bands
1 = extended in soft (0.5-2keV) band; point-like in other bands
2 = extended in full (0.5-10keV) band; point-like in other bands
3 = extended in hard (2-10keV) band; point like in other bands
4 = extended in soft and full bands; point-like in hard band
5 = extended in soft and hard bands; point-like in full band
6 = extended in hard and full bands; point-like in soft band
Note (2): If source is found in archival XMM observations, 'InXMM' is set to
'yes' and record number of XMM source is given. If source is found in archival
Chandra observations, 'InChandra' is set to 'yes' and the MSID number(s)
of corresponding Chandra source(s) is (are) given.
Note (3): det_ml≥15 in at least one band for source to be included in the
catalog, and for luminosities to be reported in the catalog for that band.
Note (5): magnitude from profile-fitting photometry unless the WISE_ext flag is
set to 'yes', in which case the magnitudes are associated with elliptical
apertures
Note (6): WISE magnitude if upper limit if SNR<2.
Note (7): If non-null, the multi-wavelength counterpart was promoted as a match
since the same X-ray source detected in the XMM archival catalog, and
matched independently to multi-wavelength catalogs, was found to have a
reliable counterpart.
Flag indicates which multi-wavelength counterpart is such a promoted match:
1 = SDSS counterpart found but photometry rejected for failing quality
control checks
2 = SDSS
3 = redshift
4 = WISE counterpart found but rejected for failing quality control checks
5 = WISE
6 = UKIDSS
7 = VHS
8 = GALEX
Note (8): Same as note 7, but for promoted matches found from the archival
Chandra catalog.
Note (9): Set to 0 if multi-wavelength counterpart coordinates are consistent
within 2" (SDSS, UKIDSS, VHS, FIRST) or 3" (WISE, GALEX, Herschel);
otherwise flag is set to 1.

--------------------------------------------------------------------------------
Note (1): Flag to indicate if source is extended as follows:
0 = point-like in all bands
1 = extended in soft (0.5-2keV) band; point-like in other bands
2 = extended in full (0.5-10keV) band; point-like in other bands
3 = extended in hard (2-10keV) band; point like in other bands
4 = extended in soft and full bands; point-like in hard band
5 = extended in soft and hard bands; point-like in full band
6 = extended in hard and full bands; point-like in soft band
Note (2): If source is found in archival XMM observations, 'InXMM' is set
to 'yes' and record number of XMM source is given. If source is found in
archival Chandra observations, 'InChandra' is set to 'yes' and the MSID
number(s) of corresponding Chandra source(s) is (are) given.
Note (3): Source is removed from LogN-LogS relationship if it is target of
archival observation or if the observation overlaps the AO13 coverage area.
Note (4): det_ml≥15 in at least one band for source to be included in the
catalog, and for luminosities to be reported in the catalog for that band.
Note (6): magnitude from profile-fitting photometry unless the WISE_ext flag is
set to 'yes', in which case the magnitudes are associated with elliptical
apertures
Note (7): WISE magnitude is upper limit if SNR<2.
Note (8): If non-null, the multi-wavelength counterpart was promoted as a match
since the same X-ray source detected in the Chandra archival catalog, and
matched independently to multi-wavelength catalogs, was found to have a
reliable counterpart.
Flag indicates which multi-wavelength counterpart is such a promoted match:
1 = SDSS counterpart found but photometry rejected for failing quality
control checks
2 = SDSS
3 = redshift
4 = WISE counterpart found but rejected for failing quality control checks
5 = WISE
6 = UKIDSS
7 = VHS
8 = GALEX
Note (9): Same as note 8, but for promoted matches found from the XMM AO13
catalog.
Note (10): Set to 0 if multi-wavelength counterpart coordinates are consistent
within 2" (SDSS, UKIDSS, VHS, FIRST) or 3" (WISE, GALEX, Herschel);
otherwise flag is set to 1.
