General Catalogue of Stars

The general Catalogue reported here has been Compiled on the basis of the preliminary catalogues consisting of the long series observations of the fundamental programs (mainly of FK4 stars) of the Mark I photoelectric astrolabe of Shaanxi Astronomical Observatory and Mark II photoelectric astrolobes of Beijing, Shanghai and Yunnan Astronomical Observatories, together with a large amount of observations of catalogue stars carried out in Beijing, Shanghai and Shaanxi, as well as 4 preliminary catalogues of Danjon's astrolabes derived from the observations of OPL No.14 of Shanghai, No.30 of Beijing and No.29 of Wuchang.

With magnitudes ranging from 0.1 to 7.2, the GCPA consists of 1579 stars. The declinations are from -3.6 degree to 68.8 degree, in which 642 are FK4 stars. The mean precisions of position corrections are 3.3 ms and 0.058" in right ascension and declination, respectively.
