Determination of Systematic Errors of Star Catalogs Using Positional Observations of Numbered Minor Planets

Transactions of IAA RAS, issue 30, 41–48 (2014)

Keywords: systematic errors of star catalogs, improvement of orbits, numbered asteroids

Abstract

Improving the orbit of 356,968 numbered asteroids enabled us to calculate systematic biases in the star catalogs USNO A2.0, UCAC-2 and UCAC-3 from the calculated О — С values. The celestial sphere was divided into 10,212 sectors which were identical in size and area. Each of the 70 234 284 observations made after 2001 was referred to a certain sky sector. The biases in the star catalogs were calculated for each sector as the arithmetic mean values of the corresponding . The variability rates of the USNO A2.0 catalog systematic errors were defined for some celestial sphere sectors.
