A CCD COLOR-MAGNITUDE STUDY OF 47 TUCANAE.
Abstract
CCD photometry in B and V is reported for 8800 stars in the field of 47 Tuc. The data, reduced through the DAOPHOT code, comprise results from two long-exposure frame pairs in which the photometry extends from the cluster turnoff down to V ≡ 24, and two other short-exposure fields nearer to the cluster center which precisely define the giant and horizontal branches. Color-magnitude diagrams are presented, statistically corrected for background …
