Abstract: One of the principal objectives of the Chandra Multiwavelength Project (ChaMP) is the optical identification and cataloging of serendipitously detected background X-ray sources in Chandra archival data. The ChaMP uses a program of multi-filter optical imaging of observed Chandra fields to detect optical counterparts to X-ray sources. We describe the methods used for reduction, analysis and cataloging of optical sources in the ChaMP fields. Automated pipeline processing of the optical data includes source extraction, photometric calibration and optical to X-ray source matching. Visual inspection tools have been developed for quality control of the resultant source lists and for identification of interesting objects for follow-up spectroscopic observations. Methods and tools for management, presentation and access of the ChaMP catalogs are also described.
