Meridian Observations, Positional Data

Scientific paper

The fifth annual catalog of the Tokyo PMC is presented for 3466 stars (Part I and Part II) which were observed at least two times in the 1989 period, that is, from January 1, 1989, to December 31, 1989. The positions of the stars given in the catalog are those at the mean epoch of observations. The coordinates of the catalog are based on the FK5 system, and refer to the equinox and equator of J2000.0. The values of (O-C)s in the catalog are calculated by using the positions given in the source catalog, and by evaluating those at the mean epoch of observations of each star, with the equinox and equator at the mean epoch. The magnitudes of the stars given in the catalog can be transformed into the V-magnitude of the standard UBV system by the equation: V = V(TPMC) + 0.063 ( B-V ) - 0.045. The mean trends of the observed positions-FK5 positions for the basic FK5 stars are constructed and compared with those of the Tokyo PMC Catalogs 86, 87, and 88. The Part I of the catalog contains the positions of 1080 basic FK5 stars, 210 FK4 Suppl. stars, 1700 AGK3R stars, 131 OB stars, 36 NPZT stars, and 96 SAO stars, observed with the Tokyo PMC in the 1989 period based on FK5 system. The Part II of the catalog contains the positions of 210 zodiacal stars observed with the Tokyo PMC in the 1989 period based on the FK5 system. The stars of the Part II are usable for the reduction of lunar occultation. The Parts I and II are concatenated to form a single machine-readable catalog. (1 data file).
