The Tokyo PMC Catalog 90-93: Catalog of Positions of 6649 Stars Observed in 1990 through 1993 with Tokyo Photoelectric Meridian Circle Yoshizawa M., Suzuki S. <Publ. Nat. Astron. Obs. Japan 5, 1 (1997)> =1997PNAOJ...5....1Y
ADC_Keywords: Meridian observations ; Positional data Description: The sixth annual catalog of the Tokyo PMC is presented for 6649 stars which were observed at least two times in January 1990 through March 1993. The mean positions of the stars observed in the above period are given in the catalog at the corresponding mean epochs of observations of individual stars. The coordinates of the catalog are based on the FK5 system, and referred to the equinox and equator of J2000.0. The mean local deviations of the observed positions from the FK5 catalog positions are constructed for the basic FK5 stars to compare with those of the Tokyo PMC Catalog 89 and preliminary Hipparcos results of H30. The catalog contains the positions of 1180 basic FK5 stars, 322 FK4 Suppl. stars, 3132 AGK3R stars, 141 OB stars, 252 NPZT stars, and 1601 SAO stars observed with the Tokyo Photoelectric Meridian Circle in the 1990 to 1993 periods based on the FK5 system. The positions of the stars are given for the mean epoch of the observations of individual stars referring 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.

Note (1): Besides obvious standard designations, AGK3 : star numbers are composed as DDNNNN, H2O : Unpublished list of H2O masers and related objects; star numbers are preliminary number in an observing list, OB : "Catalog of O-B Stars Observed with Tokyo Meridian Circle" (Yasuda+ 1986), N.B.: star numbers are not the catalog numbers but the OBSNO's deducted by 15000 (OBSNO: preliminary star number in an observing program), PZT : "Northern PZT Star Catalog" (Yasuda+ 1982), N.B.: star numbers are not the catalog numbers but the OBSNO's, which are preliminary star numbers in the Northern PZT Star list. Note (2): BD number for Dec. > -23 degrees, and CD number for Dec. < -23 degrees, component designations "p, s, x" are those used in PPM catalogues (I/146, I/193, I/208) Note (3): An asterisk at byte 134 indicates that the entry is an unresolved double star which has two AGK3 numbers, i.e. "+41 1873" and "+41 1874".
