INTEGRATED BVR PHOTOMETRY OF HALO GLOBULAR-CLUSTERS IN M31 .2.

We present new BVR integrated magnitudes and color indices for 41 glob ular clusters and cluster candidates in the outer halo of M31, obtaine d by CCD imaging at the KPNO 0.9 m telescope. This material is combine d with our previous CCD photometry for 75 cluster candidates [Reed et al., AJ, 103, 824 (1992)] and with other data from the literature to c onstruct a combined sample of globular clusters in the halo of M31 whi ch has an unprecedented level of completeness, accuracy, and freedom f rom contamination. The cluster luminosity distribution is presented an d compared with the GCLF of the Milky Way. We also use the cluster col or indices and spectra for 64 clusters to derive a metallicity distrib ution for the M31 halo. In accord with previous authors, we find that the cluster-to-cluster range in metallicity is nearly identical to tha t in the Milky Way cluster system, but that M31 has relatively more cl usters at the high-metallicity end even at large distances in the halo .
