Abstract:
Proper motions with values ≥10 or ≤10mas/yr have been extracted from
the USNOB1.0 and Tycho2 catalogs for all Lanning UV-bright sources
identified in the Sandage Two-Color Survey of the Galactic Plane and
presented in Papers I-VI (Cat. II/257. Of the 572 sources examined,
we find at least 213 that exhibit a significantly large proper motion.
Based on the location of the sources in a reduced proper motion
diagram, we demonstrate that about two-thirds of the high proper
motion sources are likely or very likely to be heretofore unidentified
white dwarfs.
