[130.05] HST photometry of the Orion Nebula Cluster

V. Kozhurina-Platais, M. Robberto, L. E. Bergeron, M. McMaster, D. Soderblom, K. Smith (STScI)

The main data product of the HST Tresasury Project on the Orion Nebula Clusters is the photometric catalog of the cluster members. Due to a variety of factors, e.g. wide field size, background contamination and presence of circumstellar emission, standard photometric techniques may not preserve the intrinsic accuracy of the HST photometry. We illustrate the strategy we have adopted to identify the sources and derive their photometry.
