Free format text (please update) Palomar 5 appears to represent an extreme in the dynamical evolution of globular clusters. A low mass, large core radius, and a low central concentration suggest that Pal 5 has lost a large fraction of it's initial mass and has expanded as a consequence. If the dynamical evolution of Pal 5 has been dominated by the effects of star loss, then theoretical arguments suggest that the stellar mass function should be deficient in low-mass stars. From a dynamical study of NGC 5466 Pryor et al. concluded that the best fitting King-Michie models for that cluster are those which have a cutoff in the stellar mass function at about 0.4 solar masses. A similar or even more extreme truncation in the Pal 5 mass function is possible. We propose to directly test this conclusion by determining the stellar luminosity function of Pal 5 down to V = 27.0 from WFPC2 F555W and F814W frames. Two fields within Pal 5 will be observed, one located near the cluster center and the other just within the half-light radius. A magnitude of V = 27.0 in Pal 5 corresponds to a stellar mass of about 0.3 solar masses, which is fainter than the predicted truncation mass. Questions ! Free format text (please update) Observing_Description: Images through the F555W and F814W filters are to be obtained of two fields in Pal 5. Exposures will be accumulated over a period of two orbits through each filter per field. One field will be centered on the center of the cluster, and the other centered just within the half-light radius. Real_Time_Justification: None. Calibration_Justification: !
