Abstract
The results are reported of an objective-prism survey of stars, mostly earlier than spectral type F5, for two fields at (l;b) = (90° and 270°; − 45°).The fields, each of approximately 70 square degrees, are examined on plates taken with the Schmidt Telescope of the Anglo-Australian Observatory. The brightness range of the stars classified is 10 < V < 15. The prism combination used provides a dispersion of 600 A/mm at H γ . The spectral classification presented is defined by the equality of equivalent widths of Ca II K and H∂ at type F0 and the absence of Ca II K in stars with significant Balmer lines at type A0. Positions listed in the catalog were measured on the Stromlo PDS microdensitometer
