HST-NICMOS Observations of M31's Metal Rich Globular Clusters and Their Surrounding Fields: II. Results

We have obtained HST-NICMOS observations of five of M31's most metal rich globular clusters: G1, G170, G174, G177 and G280. For the two clusters farthest from the nucleus we statistically subtract the field population and estimate metallicities using K-(J-K) color-magnitude diagrams (CMDs). Bas...
