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.
| The determination of the zero point of the wavelength scale on stellar spectrograms
A novel method for determining the zero point of the wavelength scale(lambda0) on low-spectral-resolution spectrograms obtainedwith an objective plasma is presented. The method was applied to a groupof 100 stars belonging to the B-G spectral classes. Near-UV spectrogramsof these stars were obtained by the Orion-2 space observatory.Equivalent widths were obtained for the resonance doublet of Mg II 2800A in the spectra of the stars studied.
