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.

BVRIJHK photometry of RR Lyrae variables
BVRI and JHK photometry are presented for the PR Lyrae variables SWAndromedae and TU Ursae Majoris. BVRI photometry is also presented forthe TT Lyncis and T Sextantis variables and two JHK points for UUVirginis. These 331 observations can be phase-locked to radialvelocities given by Barnes et al. (1988) and by Wilson et al. (1989).Attention is also given to new observations of TU UMa in the context ofthe binary model proposed by Saha and White (1990).

Contemporaneous photometry and radial velocities of RR Lyrae stars
Contemporaneous BVRI photometry and radial velocities of seven RR Lyraevariables covering nearly the full span in Delta S and including the RRcstar T Sex are reported. Over 3000 BVRI measures at 100 s timeresolution and over 400 radial velocity measures are included. Thephotometric uncertainties are of order + or - 0.007 mag in V, (B - V)and (V - R) and + or - 0.014 in (R - I). The radial velocityuncertainties range from + or - 3.8 to + or - 8.0 km/s, correlated withthe metal deficiency. Light, color, and velocity curves are given.

A new list of 617 radial velocities in four galactic fields
Four stellar fields in the -30 deg galactic latitude have been surveyedfor radial velocities, using a 62 cm objective prism. Exact positions,spectral types, and approximate magnitudes are provided for 617 stars infour different 4 x 4 deg fields. B to F4 stars were found which haveGaussian velocity distributions.

VRI photometry of selected SAO stars
Johnson V, R, and I photoelectric photometry has been obtained for 199SAO stars in support of the Near Infrared Photographic Sky Survey. Thesedata are utilized in the calibration of survey photographs and arepresented here to assist other programs reliant upon access tophotometry in the photographic infrared.
