Catálogo preliminar de radio-estrellas Nº 2 #J2000.0

Document type: Comunicacion

Abstract

Since 1987, radio stars are being systematically observed with our Repsold meridian circle (190mm) set up in San Juan , Argentina (latitude =-31° 30' 38".5 ; longitude -68° 37' 12".0). The catalogue contains optical positions of 233 radio stars, located south of δ= +40° and brighter than visual magnitude mv = + 10.0. Results of radio star observations, made during 1988, are presented as a preliminary catalogue. Each star was observed 3 times, on average, and the mean errors of one observation of the catalogue for an equatorial star resulted Sα =0.023s Sδ=0.43". The preliminary term means that the catalogue is in the instrumental system, and corrections to bring it to FK5 were not applied.
