Description
The present catalog summaries the results of a survey carried out on one of the deepest X-ray field observed by the XMM-Newton satellite. The survey is made by 13 observations taken over 2 years with a total exposure time of 1.75Ms (1.372Ms for flare-filtered) in a field of 30'x30' around the blazar 1ES 1553+113. Using a conservative threshold of Maximum Likelihood significance of ML>=6, we detected 301 X-ray point-sources, for which we derived positions, fluxes at different bands and hardness ratios. Thanks to an optical follow-up by the Gran Telescopio Canarias (GTC) over the same field in u'g'r'i'z' bands, we obtained an optical source list of 43,068 elements with photometric redshift. We cross correlated this optical source list and an infrared catalog obtained by WISE with photometric measurements in the W1, W2, W3 and W4 bands, with our X-ray catalog. We identified optical/IR counterpart candidates for our X-ray sources and we estimated their X-ray luminosities, redshift distribution, X-ray/optical flux ratio and absolute magnitudes. Additionally, we identify a subset of 204 AGNs, for which we classified as: Quasar, Seyfert galaxies and Low Luminous AGNs (LLAGNs), based on their luminosities.
