Abstract

The catalog of positions of 1007 stars (792 FK4 and FK4S stars, 57 OB stars, 49 NPZT stars, and 109 SAO stars) is presented. They were observed during the period from December 1984 to September 1985 with the Tokyo Photoelectric Meridian Circle (Tokyo PMC). The positions in the catalog are referred to the equinox and equator of J2000, and are based on the FK4 system. The internal errors of a single observation were estimated to be (epsilon(alpha)*cos(delta), epsilon(delta)) = (0.16", 0.19"), whereas the mean internal errors of the catalog positions were (0.08", 0.08") for FK4 stars and (0.09", 0.11") for FK4S stars. The comparison of the positions of the FK4 stars in the present catalog with those of the FK4 catalog shows the significant differences delta(alpha(delta)) and delta(delta(delta)) in some declination zones. Some of those differences are commonly found in other recent catalogs. Thus they may be considered to be the real systematic errors in the FK4 system. Neither significant magnitude nor color equation exists in the Tokyo PMC85 catalog.
