ADC_Keywords: Stars, variable ; Photometry Keywords: catalogs - astronomical databases: miscellaneous - stars: variables: general - techniques: photometric Abstract: The Optical Monitoring Camera (OMC) onboard the High-energy INTEGRAL satellite provides photometry in the V Johnson band. OMC is able to detect optical sources brighter than around V∼18, from a previously selected list of potential targets of interest. The first catalogue of variable sources observed by OMC has been developed with observations from October 2002 to February 2010. For each object in the catalogue, the median of the visual magnitude, the magnitude at maximum and minimum brightness in the light curve during the window of observations and the period, when found, are provided. Description: The OMC-VAR catalogue contains 5263 sources classified as variable, for 1337 of which the periods have been determined. Types of variable objects in the catalogue include eclipsing binaries, pulsating stars, rotating stars, eruptive stars, extragalactic objects, X-ray binaries, cataclysmic variables, Be stars and other objects with unknown kind of variability. Charts for each object including the DSS image around the target, the unfolded and folded light curves with the periods we have derived and/or with the catalogued ones can be retrieved from the OMC-VAR home page.

Note (1): Ten categories defined as eclipsing, pulsating, rotating, eruptive, cataclysmic, Xbinaries, Be, extragalactic, varstar and other. Note (2): 3 digits, one for each method, with the following meaning: 1 = source is not contaminated 2 = source is contaminated 3 = no photometric information has been found for that sources. See Sect. 3.4 of the paper for details about the 3 methods (usage of UCAC3 (I/315), Simbad, or VSX (B/vsx)).
