Abstract: The OMEGACAM wide-field imager will start operations at the ESO VLT Survey Telescope at Paranal in 2007. The photometric calibration of OMEGACAM data depends on standard-star measurements that cover the complete 1°×1° FOV. A catalog fullfilling this requirement for 8 Landolt equatorial fields, denoted the OMEGACAM Secondary Standards Catalog, will be constructed from OMEGACAM observations during the first year of operations. We present the ‘Preliminary Catalog’ which will be used to bootstrap the construction of the OMEGACAM Secondary Standards Catalog. Thus the Preliminary Catalog will be used to assess the performance of OMEGACAM+VST early-on. The catalog is based on WFC data from the INT.
