UCAC3 Proper Motion Survey. 2. Discovery of New Proper Motion Stars in UCAC3 with 0'.40 yr-1 > micro > or = 0'.18 yr-1 between Declinations -47 deg and 00 deg

摘要

The third U.S. Naval Observatory (USNO) CCD Astrograph Catalog (UCAC3) (Zacharias et al. 2010) proper motion survey addresses the possibility that proper motion surveys using digitized scans of photographic plates might overlook some proper motion systems. The UCAC3 obtained accurate proper motions by combining CCD observations with early epoch photographic data. This survey utilizes the UCAC3 proper motions to discover new systems that have been missed in previous efforts.
