November 1st, 2011 - NEW !!

Updated XMM-COSMOS table of the 1797 primary X--ray counterparts, including new redshifts from ongoing (mostly DEIMOS/KECK) spectroscopic campaigns and few changes in published redshifts and/or spectroscopic classifications from a re-analysis of the data.
New table available here, and a logfile with all the changes detailed available here
The README file of the catalog is the same as the published one (see below), and it is available here



XMM-COSMOS Survey

53 FIELDS XMM source list

Here you can find the relevant information about the optical counterparts for the sources detected in the XMM-53 fields observations (status: as of 1st, April, 2010 - this table was used in the paper Brusa et al. (2010))

1)
The file xmm53fields_table.dat (ASCII format) contain 1797 rows corresponding to the number of all the pointlike sources detected in the 0.5-2 (1545 sources), 2-8 (1078 sources) and 4.5-10 (246 sources) keV bands, with a detection significance greater 10 (DET_ML>10).
The source lists have been generated with the EBOXDETECT tool by XMM-SAS with some implementation specifically designed for the large area and the large dataflow of COSMOS by Nico Cappelluti and Hermann Brunner. The images, exposure maps and background maps used for the detection run are available as a gzipped tar file here).

For each source the information retrieved from the X-ray source list (XID, fluxes, HR) in the different bands, and the identification work (most likely optical id counterpart, flag of identification, coordinates, id from optical catalogs, spectro-z and photoz) are reported.
The README file contains the explanation of all the columns.

The file xmm53fields_table_all.dat (ASCII format) contains, at the end of the file, additional 203 rows corresponding to the properties of the second likely counterparts in the cases of "ambiguous" sources.

2)
At the following links you can find the tar files of all the cutouts around the X-ray sources in the:
Subaru I-band
HST/ACS
K-band
IRAC (4 different channels)
GALEX (2 different filters, NUV and FUV)
Each cutout is uniquely identified by the XID number.
