Description:
The Lick Northern Proper Motion (NPM) program measured proper motions,
positions, and photographic photometry for some 149,000 stars (NPM1
Catalog) covering the sky outside the Milky Way north of declination
23 degrees. The NPM1 proper motions were measured with respect to an
absolute reference frame defined by some 50,000 faint galaxies (mostly
16 < B < 18 mag). The rms position errors for the NPM1 reference
galaxies average 0.2 arcsec. The rms errors for the B magnitudes average
0.25 mag.
More complete descriptive information is available in the ASCII or
LaTeX documentation written by R.B. Hansen (UCO/Lick Obs.).
