UBV Photometry of Faint Stars (V>14.5) in M67

This catalog is the result of a program of photographic photometry. Four plates each were taken of M67 in U, B, and V, and were measured and reduced using the standards of Johnson and Sandage (1955) and Eggen and Sandage (1964). The catalog lists identification, V, B-V, U-B, proper motion, and membership probability for 1,053 stars. Introduction: The UBV Photometry of Faint Stars (V>14.5) in the Open Cluster M67 (NGC 2682) (UBV-M67; Frolov and Ananyevskaya 1986) lists UBV photometry of faint stars obtained as part of an investigation of M67. It complements the work of Frolov (1984), which dealt with the brighter stars (V '<' 14.5 mag.) Because most of these objects had no previous photometry, Frolov and Ananyevskaya have obtained UBV photometry for all catalog stars. Four plates were taken in each color using the Schmidt telescope of the Radio Astrophysical Observatory of the Latvian SSR, which were then measured and calibrated using the standards of Johnson and Sandage (1955) and Eggen and Sandage (1964). Frolov and Ananyevskaya (1986) note the following: As there was a lack of the faintest standards we had to add photoelectric UBV magnitudes of five stars determined only by one observation. The mean errors are 0.03, 0.04, and 0.03 mag. for U, B, and V magnitudes, respectively. See Frolov (1984) for further details of the data reduction. Of the 1,053 stars included in this catalog, 172 were determined to be members of M67 on the basis of proper motion and photometry. The catalog is in a single file which lists identification, V, B-V, U-B, relative proper motion, and probability of membership for each of the stars investigated.
