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.
