XMMOMCDFS ivo://nasa.heasarc/xmmomcdfs NASA/GSFC HEASARC Antonucci et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source The XMM-Newton X-ray observatory has performed repeated observations of the Chandra Deep Field-South (CDFS) in 33 epochs (2001 - 2010) through the XMM-CDFS Deep Survey (Comastri et al. 2011, A&A, 526, L9). During the X-ray observations, the XMM-Newton Optical Monitor (XMM-OM) targeted the central 17 x 17 arcmin<sup>2</sup> region of the X-ray field of view, providing simultaneous optical/UV coverage of the CDFS. The resulting set of data can be taken into account to build an XMM-OM catalog of the CDFS, filling the UV spectral coverage between the optical surveys and GALEX observations. This table contains the UV catalog of the XMM-CDFS Deep Survey. Its main purpose is to provide complementary UV average photometric measurements of known optical/UV sources in the CDFS, taking advantage of the unique characteristics of the survey. The data reduction is intended also to improve the standard source detection on individual observations, by cataloguing faint sources through the stacking of their exposure images. The authors reprocessed the XMM-OM data of the survey and stacked the exposures from consecutive observations using the standard SAS tools to process the data obtained during single observations. Average measurements of detections with SAS good quality flags from individual observations and from stacked images have been joined to compile the catalogue. Sources have been validated through the cross-identification within the ESO Imaging Survey (EIS: Arnouts et al. 2001, A&A, 379, 740) and COMBO-17 (Wolf et al. 2004, A&A, 421, 913; 2008, A&A, 492, 933) surveys. Photometric data of 1129 CDFS sources are provided in the main catalog, and optical/UV/X-ray photometric and spectroscopic information from other surveys are also included. The stacking extends the detection limits by ~1 mag in the three UV bands, contributing 30% of the catalogued UV sources. The comparison with the available measurements in similar spectral bands confirms the validity of the XMM-OM calibration. The combined COMBO-17/X-ray classification of the "intermediate" sources (e.g. optically diluted and/or X-ray absorbed AGN) is also discussed in the reference paper. This table was created by the HEASARC in June 2015 based on the union of <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/217/4/">CDS Catalog J/ApJS/217/4/</a> files omcdfst7.dat (the 1,129 sources in the main catalog) and omcdfst8.dat (the 44 sources in the supplementary catalog).
