Detection of the delta Scuti Oscillation in RZ Cassiopeiae
PMT and CCD photometry of the RZ Cas were carried out. The 22-minperiodic oscillations with amplitude of about 20-mmag amplitude weredetected not only in primary minimum but also in secondary minimum andin out-of-eclipse. The oscillations should be the Delta Scutivariability.
| 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.
