Description:
This Catalogue was created for geodetical purposes, mainly for the
determination of the latitude by Talkott's method. It contains all
stars up to 6 vis. mag. from -10 to +90 degrees. It is composed of
1334 "geodetic" stars and 1623 "Pulkovo" stars.
The "geodetic" stars were observed on 5 observatories (Pulkovo, GAISH,
Kazan, Nikolaev and Tashkent) by differential methods: each star was
observed 8 times in the system of "Pulkovo" stars, during years
1934-1939.
The Catalogue of 1623 "Pulkovo" Stars was observed in the years
approx. 1910-1925 in Pulkovo, Alger, Babelsberg, Washington,
Greenwich, Cape, Nicolaev, Paris and Uccle, mainly by absolute
methods.
There are corrections to FK3 for each star.
