Scientific paper

Deep V and B photometry for the outer-halo cluster Palomar 5 (C1513 + 000) has been obtained with the prime-focus CCD camera at the CTIO 4 m telescope. The color-magnitude diagram reaches several magnitudes below the main-sequence turnoff, the first diagram to be obtained to such faint intrinsic magnitudes for one of the anomalous Palomar clusters. Although this is a sparse cluster, no evidence for a binary sequence was detected like that found by McClure et al. for E3, a halo cluster with similar morphology. The luminosity function on the main sequence shows a turnover like that found for E3, however. This implies a mass function with a very low power-law index, which indicates either that there has been considerable dynamical evolution in the cluster or that the initial mass function had a very peculiar form. The matching of the observed color-magnitude diagram with theoretical isochrones is discussed.
