A Homogeneous System of Secondary Spectrophotometric Standards of Intermediate Brightness
Abstract
A program for setting up a system of secondary spectrophotometric standards in the northern sky is described. The standard stars are situated in three zones: north of +85(deg) (14 stars), at +40(deg) (22 stars) and at the celestial equator (43 stars). The stars are of 7--9 magnitudes and their energy distribution curves cover 310--755 nm spectral range.
