Abstract

The Optical Monitoring Camera (OMC) onboard INTEGRAL (launched on October 17, 2002) has been designed to obtain V-Johnson photometry simultaneously with high energy observations at X-ray (3–35 keV) and (15 keV–10 MeV) performed by the main instruments onboard INTEGRAL. Due to technical limitations on the data processing electronics and the available telemetry, it is necessary to know, a priori, the objects to be monitored within the field of view (FOV) of the OMC. The OMC Input Catalogue – and subsequent provides this information: astrometric and photometric reference stars for calibration and scientific targets for accurate photometric variability studies.
