We present positions and magnitudes of stars and star clusters in a 1° × 1° area centered on M33. The survey is based on deep archival ground-based images using the MegaPrime camera on the 3.6m Canada-France-Hawaii telescope. We provide u′, g′, r′, i′, z′ magnitudes by performing standard profile-fitting photometry of these images and apply image classification algorithms such as SExtractor. We also present a catalog of extended sources by applying visual-inspection classification. This complete catalog provides promising targets for deep photometry with HST and for high-resolution spectroscopy to study the structure and star-formation history of the disk and halo of M33.
