Second Rio Grande catalogue (RG2). (1990). Revista Mexicana De Astronomía Y Astrofísica, 21(1), 286. https://astronomia.unam.mx/journals/rmxaa/article/view/1990rmxaa..21..286h
Abstract
The RG2 catalogue was observed at Rio Grande station (-54°; -4h31m) with the Danjon Astrolabe OPL 01. It contains corrections to 122 FK4 and FK4 Sup. stars with declinations ranging from -27° to -80°, mean epoch 1986.0 and reference system J2000. It was used the classical reduction method given by Guinot (1955). Group corrections were obtained by the chain method.Similar Articles
