Abstract:
We present the final release of the multiwavelength XMM-Large Scale
Structure (LSS) data set, covering the full survey area of 11.1deg2,
with X-ray data processed with the latest XMM-LSS pipeline version.
The present publication supersedes the catalogue from the first paper
in this series, pertaining to the initial 5deg2. We provide X-ray
source lists in the customary energy bands (0.5-2 and 2-10keV) for a
total of 6721 objects in the deep full-exposure catalogue and 5572 in
the catalogue limited to 10ks, above a detection likelihood of 15 in
at least one band. We also provide a multiwavelength catalogue,
cross-correlating our list with infrared, near-infrared, optical and
ultraviolet catalogues. Customary data products, such as X-ray fits
images and thumbnail images from the Canada-France-Hawaii
Telescope Legacy Survey and the Spitzer Wide-Area Infrared
Extragalactic Survey, are made available, together with our data base
in Milan, which can be queried interactively.
Description:
We provide the source list for the full area (11.1 square degrees) of
the XMM-LSS (2xlss.dat), with a total of 5572 point-like or extended
sources above a detection likelihood of 15 in either 0.5-2 or 2-10keV
bands. The tables at CDS contains the main X-ray parameters, while
further multiwavelength parameters and data products (X-ray images and
optical/IR thumbnails) are available in the Milan XMM-LSS database
site. This 2XLSS version contains the result of the analysis in 10ks
limited exposures.

Global Notes:
Note (G1):
This note applies to all merged band columns from Xseq to XDEdeg.
Columns whose label begins with X refer to band-merged X-ray properties
and are always present for all records.
Note (G2):
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):
This note applies to all 0.5-2keV band columns from Bseq to Bfluxflag.
Columns whose label begins with B refers to X-ray properties in the
0.5-2keV band.
If a source was not detected in the band, all these columns are blank.
Note (G4):
The C1/C2 classification flag is set for candidate clusters according to
ref. (1) and assumes the following values
1 = object classified as C1 cluster candidate in the 0.5-2keV band
2 = object classified as C2 cluster candidate in the 0.5-2keV band
0 = undefined in any other case
Note (G5):
The soft or hard band core radii can assume value -1 when the extended
source fit fails in the relevant band.
Note (G6):
This note applies to all 0.5-2keV band columns from BRAdeg to Bfluxflag,
and similarly to all 2-10keV band columns from CDRAdeg to CDfluxflag.
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 (G7):
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 (G8):
The flux is set to -1.0 when undefined for any reason (in particular
it is set to undefined for all C1 clusters)
Note (G9):
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 (G10):
This note applies to all 2-10keV band columns from CDseq to CDfluxflag.
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.
Note (G11): (Xlsspointr)
A non-zero value contains the Xseq of the corresponding source in the
Version I XLSS catalogue (Pierre et al. 2007, Cat. J/MNRAS/382/279)
Note (G12):
The absolute value of Xdeep, if non-zero, contains the Xseq of the
corresponding source in the deep catalogue 2XLSSd
