I/186         Tokyo Photoelectric Meridian Circle Catalog 1985 (Yoshizawa+ 1987)

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
