Abstract

Photometric data on the Johnson-Morgan B, V system are given for 1401 stars in the cluster area. Differential reddening exists across the cluster region and ranges from a minimum value of E(B-v) = 0.29 magnitudes to a maximum of E(B-v) = 0.60 magnitudes. A distance modulus of 9.0 + 0.2 magnitudes was derived through the utilization of the Johnson evolutionary deviation curve method. There appear to be two G-type red-giant members of the cluster in addition to the 6.7-day classical cepheid U Sagittarli. The chister luminosity function was studied to Mv = +5.0 and tends to agree with the Salpeter initial luminosity function.
