Optical positions of radio stars observed with the meridian circle of the Real Instituto y Observatorio de la Armada en San Fernando.
Abstract
Positions of 53 radio stars are presented. The positions of the radio stars are for the epoch of observation and the equinox J2000.0 and are in a system close to that of the FK5. The limiting magnitude is V = 9.5. The observation of transits of the stars is visual but automatically recorded, a photoelectric circle reading system stores the positions of the divided circle directly in computer memory. The mean error of a single observation in the zenith is 0s018 in right ascension and 0″38 in declination. Comparisons are given of the catalogue with the FK5 and of radio star positions with those of the Carlsberg Meridian Catalogue La Palma no.4 (CMC4). Cross-references are given to FK5, SAO and DM catalogues.
