A Comparison of AGK3 with NPZT:74 Catalog
Abstract
Systematic differences in relation to right ascension, declination, magnitude and spectral type between the two catalogs are presented. The effects of errors of AGK3 on photographic determination of positions of extragalactic radio sources are discussed. The conclusion is that it is necessary to establish a homogeneous, precise faint reference stars system.
