The authors analyzed the images of the Galactic Center region obtained with the ISGRI detector of the IBIS telescope (15 - 200 keV) and this table contains their catalog of detected sources. A total of 60 sources with fluxes above 1.5 milliCrab were detected in the range from 18 to 60 keV (1 mCrab = 1.36 x 10<sup>-11</sup> erg/s/cm<sup>2</sup> in this energy band for a source with a power-law spectrum with a photon index of 2.1) above a detection threshold of 6.5 sigma which was chosen to avoid the strong effect of systematic uncertainties. The nature of 51 of the 60 sources is known: most of them (38 of 51) are low-mass X-ray binaries, and the remaining 13 include 5 high-mass X-ray binaries, 2 cataclysmic variables, an anomalous X-ray pulsar, a soft gamma repeater and three extragalactic objects. This table was created by the HEASARC in February 2005 based on <a href=\"https://cdsarc.cds.unistra.fr/ftp/cats/J/PAZh/30/430\">CDS Catalog J/PAZh/30/430</a> (the catalog.dat file).
