VizieR Online Data Catalog: F2-G5 Stars in a North Galactic Pole Region (Upgren 1963)

The catalog is an objective-prism survey for stars of spectral classes F2 to G5 in a region of high galactic latitude. The catalog contains 1127 stars and is complete to a limiting photographic magnitude of 12.5. The photographic plates used permit a separation of the stars into narrow and well-defined spectral classes. The spectral classification of the stars in the catalog is based on the Yerkes MK system. The catalog is subdivided into one-degree declination zones as are the DM catalogs. The degree zones are based on 1855 coordinates. The catalog includes sequence numbers of the stars, BD and HD numbers, positions (B1950), B magnitudes, spectral types, and remarks.
