M5 Richer, Harvey B. ; Fahlman, Gregory G. Abstract Deep UBV CCD imagery has been obtained in three fields of the galactic globular cluster M5. The locations of these fields are at distances of 8, 21, and 58 core radii. In the middle field the CCD photometry reaches fainter than V = 26. From the color-color diagram of the cluster its metallicity is determined to be [M/H] = -1.13. The distance to M5 is then established from fitting local subdwarfs to the lower main sequence of the cluster. This yields (m-M)v = 14.30. Using the appropriate VandenBerg and Bell isochrones gives an age estimate of 17 Gyr for M5.
