FAINT HALO GLOBULAR-CLUSTERS AND THE GCLF IN M31

Short-exposure imaging with the High Resolution Camera on the CFHT has been used to classify 92 previously unstudied globular cluster candidates in the halo of M31. Of these, 14 are definite or highly probable clusters, five more are low-probability clusters, and the remainder are background galaxies or foreground stars. We combine these new objects with other published samples to produce a globular cluster luminosity function for M31 that is, for the first time, very nearly complete, uncontaminated, and photometrically accurate. The resulting GCLF is similar in shape to the Milky Way cluster distribution, though it has a narrower dispersion and its turnover (peak-frequency luminosity) is almost 0.3 mag brighter.
