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 Baade-Wesselink method and the distances to RR Lyrae stars. VI - The field stars RS Bootis, TW Herculis, VY Serpentis, and UU Virginis, and the absolute magnitudes of RR Lyrae stars
Simultaneous BVK photometry and radial velocities from high-resolutionspectroscopy are used to derive distances and absolute magnitudes forthree metal-rich RR Lyrae stars: RS Boo, TW Her, and UU Vir, using thesurface brightness version of the Baade-Wesselink method. New Kphotometry and previously published optical photometry and radialvelocities are used to perform the same analysis upon the extremevelocity metal-poor RR Lyrae variable VY Ser. The results of otherdeterminations of (MV)RR are critically reevaluated to see whether RRLyrae stars are less luminous than 0.6 mag. The results support therecent proposal that there may be a simple period-(MK) relation that isindependent of metallicity and temperature effects. Such a relationshipwould provide an improved estimate for the distance to the Galacticcenter or for any high-reddening region. The age of the RR Lyrae-richglobular cluster M5 is estimated at (18 + or - 3) x 10 to the 9th yr.
