Perth 70, A Catalogue of Positions of 24900 Stars Hog E., von der Heide J. <Abh. der Hamburger Sternw., Band IX, 15 (1976)> =1976AAHam...9....1H
ADC_Keywords: Positional data ; Proper motions Description (from ADC): This Perth 70 "A Catalogue of Positions of 24900 Stars" contains accurate positions and magnitudes of 24871 reference stars, mostly in the Southern Hemisphere, plus other useful data such as approximate proper motions, radial velocities, and parallaxes. The Perth 70 is a result of meridian circle observations made by the Hamburg Observatory expedition to Perth as part of the international effort on Southern Reference Stars (SRS). The catalog described here provides the mean values for each star, including the position, magnitude, and mean epoch of observation; the proper motions, however, were neither observed nor recomputed from comparing the Perth positions to older material.
