Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

Abstract:
The Survey Science Centre of the XMM-Newton satellite released the
first incremental version of the 2XMM catalogue in August 2008.
Containing more than 220000 X-ray sources, the 2XMMi was at that time
the largest catalogue of X-ray sources ever published and thus
constitutes an unprecedented resource for studying the high-energy
properties of various classes of X-ray emitters such as AGN and stars.
Thanks to the high throughput of the EPIC cameras on board XMM-Newton
accurate positions, fluxes, and hardness ratios are available for a
substantial fraction of the X-ray detections. The advent of the 7th
release of the Sloan Digital Sky Survey offers the opportunity to
cross-match two major surveys and extend the spectral energy
distribution of many 2XMMi sources towards the optical bands. This
implies building extensive homogeneous samples with a statistically
controlled rate of spurious matches and completeness. We here present
a cross-matching algorithm based on the classical likelihood ratio
estimator. The method developed has the advantage of providing true
probabilities of identifications without resorting to heavy
Monte-Carlo simulations.
Description:
Results of the statistical cross-match based on likelihood ratios
between the incremental Second XMM-Newton Serendipitous Source
Catalogue (2XMMi) and the Seventh Data Release of the Sloan Digital
Sky Survey (SDSS DR7). The cross-match is limited to 2XMMi point-like
sources (epextml<4) with a positional error smaller or equal to 5
arcsec, and to SDSS DR7 primary sources. We considered the individual
XMM source detection positions and errors on positions available in
the XCATDB (http://xcatdb.u-strasbg.fr/2xmmi/home).
The table contains 72169 distinct associations for 72171 rows. For
each association, the table provides: parameters extracted from the
2XMMi catalogue ; cross-match parameters ; and parameters extracted
from both the SDSS DR7 catalogue and CasJobs
(http://cas.sdss.org/CasJobs/).

Note (1): 2XMMi sumflag as follows:
0 = good
1 = source parameters may be affected
2 = possibly spurious
3 = located in a area where spurious detection may occur
4 = located in a area where spurious detection may occur
and possibly spurious
Note (2): 2XMMi hardness ratios defined as:
1 = bands 1 & 2
2 = bands 2 & 3
3 = bands 3 & 4
4 = bands 4 & 5
2XMMi Bands defined as:
1 = 0.2-0.5keV
2 = 0.5-1.0keV
3 = 1.0-2.0keV
4 = 2.0-4.5keV
5 = 4.5-12.0keV
8 = 0.2-12.0keV
9 = 0.5-4.5keV
Note (3): Type (class) from SDSS is numbered as follows:
0 = Unknown: Object type is not known
3 = Galaxy: An extended object composed of many stars and other matter
6 = Star: A a self-luminous gaseous celestial body
8 = Sky: Blank sky spectrogram (no objects in this arcsecond area)
Note (4): Flag (sc_chflag1) as follows:
1 = a 2XMM source with unchanged SC parameters
2 = a 2XMM source with changed SC parameters
3 = a new source
Note (5): Flag (sc_chflag2) as follows:
0 = depends on f1 (sc_chflag1):
* if f1=1, a unique source present in 2XMM remains unchanged
in 2XMMi when comprised only of the same detections as in 2XMM.
* if f1=2, one or more new detections in 2XMMi can, by virtue of
their spatial separation, simply associate with the group of
detections from a unique source in 2XMM.
* if f1=3, new detections in 2XMMi that do not associate with a
unique source in 2XMM form new unique sources in 2XMMi with
SRCID values >=191871.
1 = with f1=2, Detections that formed a source in 2XMM have
been regrouped, that is, while a source in 2XMMi might map to
one in 2XMM (having the same source ID and IAU name) it may have
lost detections it had in 2XMM and it may have gained old
detections from a different 2XMM source or new detections.
Note (6): Spectral class as follows:
0 = Spectrum not classifiable (zConf<0.25)
1 = Spectrum of a star
2 = Spectrum of a galaxy
3 = Spectrum of a quasi-stellar object
4 = Spectrum of a high-redshift quasar (z>2.3), whose redshift is
confirmed by a Ly-alpha estimator
5 = Spectrum of blank sky
6 = Star dominated by molecular bands M or later
7 = Emission line galaxy (placeholder)
Note (7): SDSS flags
