资源简介：
New astrometric reductions of the US Naval Observatory CCD Astrograph
Catalog (UCAC) all-sky observations were performed from first
principles using the TGAS stars in the 8 to 11 magnitude range as
reference star catalog. Significant improvements in the astrometric
solutions were obtained and the UCAC5 catalog of mean positions at a
mean epoch near 2001 was generated.
