We present the X-ray source catalog for the 479 ks Chandra exposure of the
SDSS J1030+0524 field, that is centered on a region that shows the best
evidence to date of an overdensity around a z > 6 quasar, and also includes a
galaxy overdensity around a Compton-thick Fanaroff-Riley type II radio galaxy
at z = 1.7. Using wavdetect for initial source detection and ACIS Extract for
source photometry and significance assessment, we create preliminary catalogs
of sources that are detected in the full, soft, and hard bands, respectively.
We produce X-ray simulations that mirror our Chandra observation to filter our
preliminary catalogs and get a completeness level of > 91% and a reliability
level of 95% in each band. The catalogs in the three bands are then matched
into a final main catalog of 256 unique sources. Among them, 244, 193, and 208
are detected in the full, soft, and hard bands, respectively. This makes J1030
field the fifth deepest extragalactic X-ray survey to date. The field is part
of the Multiwavelength Survey by Yale-Chile (MUSYC), and is also covered by
optical imaging data from the Large Binocular Camera (LBC) at the Large
Binocular Telescope, near-IR imaging data from the Canada France Hawaii
Telescope WIRCam, and Spitzer IRAC. Thanks to its dense multi-wavelength
coverage, J1030 represents a legacy field for the study of large-scale
structures around distant accreting supermassive black holes. Using a
likelihood ratio analysis, we associate multi-band counterparts for 252 (98.4%)
of the 256 Chandra sources, with an estimated reliability of 95%. Finally, we
compute the cumulative number of sources in each X-ray band, finding that they
are in general agreement with the results from the Chandra Deep Fields.
