Abstract:
A catalog of the O-B stars, selected from "Blaauw-Parenago" list
(1955, First IAU Symposium, "Co-ordination of galactic research") and
Rubin's catalog (1962AJ.....67..491R 1962AJ.....67..491R, Cat. V/31), has been compiled
on the FK4 system by the observations made with Gautier 8-inch
Meridian Circle at the Tokyo Astronomical Observatory during the
period, 1971 to 1979. It contains 1059 stars and was compiled for the
future establishment of high precision proper motions of O-B stars.

History:
* 18-Mar-1997: Prepared via OCR at CDS.
* 20-Mar-2005: Some number in the last column (BD) refer in fact to
the Cordoba Durchmusterung (CD) but the leading '1' for numbers
larger than 10000 was missing in the publication. 6 such numbers
were corrected.
