Abstract: |
We have obtained VI CCD photometry for the young globular clusters Ruprecht 106, Terzan 7, and Arp 2 using the 0.9m and 1.5m telescopes at Cerro Tololo Inter-American Observatory. The resulting V ~ (V-I) color-magnitude diagrams extend from the tip of the red giant branch to approximately 3 magnitudes below the horizontal branch. We have applied the SRM method of Sarajedini (1994) to the RGBs of these clusters in order to measure their reddenings and metallicities. Furthermore, we have formulated the SRM method in the V ~ (B-V) color-magnitude plane and applied it to published BV photometry for these young globular clusters. The implications of these derived parameters will be discussed. |
