Photometric Study of the Southern Open Clusters NGC 5316 and NGC 6124
Abstract
Based on UBV photoelectric photometry, the individual reddenings of cluster stars in NGC 5316 and NGC 6124 were derived, and a fitting to an evolved sequence was performed on the reddening-free colors and magnitudes of cluster members. For NGC 5316, an average distance modulus of 10.34 + or - 0.07, an E(B-V) value of 0.34 + or - 0.04 s.d., and an age of about 1.2 x 10 to the 8th yr were found. For NGC 6124, an E(B-V) value of 0.80 + or - 0.06 s.d., an average distance modulus of 8.75 + or - 0.04, and an age of about 1.0 x 10 to the 8th yr are determined. The present color excesses and distance moduli are, in general, greater than previous values.
