PHOTOMETRY IN THE OPEN CLUSTERS IC-2602 AND NGC-6475

CCD photometry has been obtained in the regions of the open clusters I C 2602 and NGC 6475 for the purpose of identifying likely optical coun terparts to x-ray sources. Photometry has also been obtained for relat ively bright stars in both clusters in order to improve upon previous photometry and to assess membership. In IC 2602, the new candidate mem bers associated with x-ray sources include two visual binary systems w ith the secondary components being the lowest-mass candidate members i dentified to date. In NGC 6475, several possible optical counterparts to the strongest x-ray source in the field of the cluster have been gi ven, though the true optical counterpart remains unknown.
