Third General Catalogue of Stars Observed with the Photoelectric Astrolabes
View through CrossRef
AbstractOn the basis of the data observed with the Photoelectric Astrolabes in China observed during the period from 1982 to 1990, the general catalogue is compiled. With magnitudes ranging from 0m.l to 7m.3, the general catalogue consists of 2577 stars spreading from δ=−3° to δ= 69°, in which 955 are FK5 stars and 1622 are GC stars. The mean precisions of 2577 Δα’s and 1892 Δδ’s are ±4.0 ms and ±0”.065, respectively. The mean epoch of the catalogue is 1987.4. Finally systematic corrections of (CAT—FK5) are given.
