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. Hanson (UCO/Lick Obs.).
