Description:
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.

Historical Notes:
* 30-Sep-1991: the catalogue was supplied to CDS by Shiro Nishimura;
the reformatting of the data were carried out at the Astronomical
Data Analysis Center of the National Astronomical Observatory, Japan.
* 20-Feb-1996: Documentation standardized, using the same description
as catalog I/198 by S.Nishimura [ADAC/NAOJ], from 01-Sept-1993
