Scientific paper

A sample survey is being conducted in UBV photometry and proper motions as part of an investigation of galactic structure and evolution. The paper discusses the observational results in a restricted field (1.78 sq deg) at intermediate galactic latitude in the direction of the globular cluster M5. The resulting catalog includes 1180 stars; it is complete down to B = 18, V = 17.4, and U = 18. The plate material has been obtained at the CERGA Schmidt telescope between 1984 and 1990. Glass copies of the Palomar Observatory Sky Survey have been used as first epoch for proper motions. The accuracy of relative proper motions is better than 3 mas/yr for stars brighter than V = 16.5. The photometric accuracy ranges between 0.08 and 0.10 in the three bands. The paper discusses the main points relevant to astrometric accuracy; digitization, the efficiency of centering algorithms, the plate-to-plate transform using orthogonal polynomials, and the effect of unmodeled distortions.
