Photographic Catalogue of 200000 Southern Stars – FOCAT–S

Abstract

AbstractThe catalogue of about 200000 stars in the zone from equator to southern pole was complied from photographic observations carried out during 1982 – 1969 years in USSR and Bolivia by Pulkovo astrograph (D=23 sm, F=230 sm, working field 4° × 4° ). The plates were measured by Zeiss Ascoreoord measuring mashines in Pulkovo, Tarija, and others observatories. The process of measurement and compilation of catalogue were carried out in Pulkovo by ES–1033 computer. The observations were made with a four–fold overlap of the sky. Reference oatalogue is SRS catalogue (FK5 system). The differencial refraction, differencial aberration and objective distortion were taken into account. The mean accuracy of catalogue FOCAT-S positions is ±0.123″.
