Proper Motions of Faint UV-Bright Sources in the Sandage Two-color   Survey of the Galactic Plane
  Proper motions with values >10 mas/yr or <-10 mas/yr have been extracted from the USNO-B1.0 and Tycho II catalogues 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 which 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.
