| Abstract | We present V,I CCD photometry of individual stars in five halo globular clusters in M31. For four clusters, the CMD shows a well-defined giant branch whose morphology is consistent with the metallicity estimates from spectroscopy of the clusters integrated light. An area of ̃10 square arcmin of the halo of M31 has also been analyzed. The mean halo metallicity is [Fe/H]̃-0.5 with a large dispersion σ[Fe/H]̃.5 dex. The distance modulus has also been estimated as (m-M)0=24.5±0.2, close to the more usual value of (m-M)0̃24.3. |
