On the SRS Catalogue [PDF]

open access: yesSymposium - International Astronomical Union, 1986
The Soviet astronomers B.P. Gerassimovich and N.I. Dneprovsky suggested in 1932 that a Catalogue of Faint Stars be compiled. The SRS catalogue is in fact a realization of this suggestion for the southern hemisphere. The final goal of the work is an international catalogue of faint stars IRS=AGK3R + SRS, containing about 40 000 stars of the 7–9th mag ...
