VizieR Online Data Catalog: USNO Saturnian observations 1974-1998 (Robert+, 2016)
Abstract
Astrometric and measured data of Saturn, Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion and Iapetus, taken with the U.S. Naval Observatory 26-inch refractor from 1974 to 1998. Astrometric (RA,DEC) positions are geocentric observed positions reduced from stars and refer to the ICRF. They were corrected for all instrumental and spherical effects, except for the light time propagation. Raw data with (x,y) positions of the stars and satellites are available on demand (Vincent Robert, vincent.robert(at)obspm.fr). (9 data files).
