The Tokyo PMC catalog 90-93: Catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo photoelectric meridian circle The sixth annual catalog of the Tokyo Photoelectric Meridian Circle(PMC) is presented for 6649 stars which were observed at least two timesin January 1990 through March 1993. The mean positions of the starsobserved are given in the catalog at the corresponding mean epochs ofobservations of individual stars. The coordinates of the catalog arebased on the FK5 system, and referred to the equinox and equator ofJ2000.0. The mean local deviations of the observed positions from theFK5 catalog positions are constructed for the basic FK5 stars to comparewith those of the Tokyo PMC Catalog 89 and preliminary Hipparcos resultsof H30.
| KPNO lunar occultation summary. II The results from 65 lunar occultation observations between August 1984and July 1986 are discussed. The instrumentation and reductionprocedures used in the study are described. Parameters are given fornine different double/multiple stars and for two stars with measurableangular diameters. Three newly discovered double stars, SAO 77310, SAO79241, and the brighter component of SAO 77837, are examined. Inaddition, a fourth star, the brighter component of SAO 76862, isresolved for the first time.
