Scientific paper

Stromgren uvby and H-beta photometry has been obtained for 37 stars in and near the region of SA 57, the Selected Area nearest the north galactic pole. These stars can serve as secondary standards for photometric work in this region. Comparisons with previous photometry shows reasonable agreement. The data are analyzed to determine interstellar reddening, metal abundances of the F-type stars, and distances. On the average, the stars are somewhat weak lined, compared to the sun. The reddening is close to zero.
