Proper Motions of Faint Ultraviolet‐bright Sources in the Sandage Two‐Color Survey of the Galactic Plane

Proper motions with values ≥10 or ≤−10 mas yr−1have been extracted from the USNO‐B1.0 and Tycho‐2 catalogs for all Lanning UV‐bright sources identified in the Sandage Two‐Color Survey of the Galactic Plane and presented in Papers I–VI. Of the 572 sources examined, we find at least 213 that exhibit a...

Summary:Proper motions with values ≥10 or ≤−10 mas yr−1have been extracted from the USNO‐B1.0 and Tycho‐2 catalogs for all Lanning UV‐bright sources identified in the Sandage Two‐Color Survey of the Galactic Plane and presented in Papers I–VI. 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.
