Description:
The Lick NPM2 Catalog provides absolute proper motions, positions, and
photographic photometry, measured in the Lick Northern Proper Motion
(NPM) program, for 232,062 stars in the magnitude range 8<B<18,
covering the sky within the Milky Way north of -23deg declination. The
NPM2 Cross-Identifications file provides 46,887 cross-identifications
between the NPM2 Catalog numbers and star names, stellar type
classifications, and publication references. These additional data,
extracted from Klemola's Lick Input Catalog of Special Stars (ICSS),
facilitate many practical uses of the NPM2 Catalog. Five Appendices to
the NPM2 Catalog provide references, footnotes, and other useful
information. This "ReadMe" file explains the file formats. Detailed
documentation is given in the file "npm2cros.txt".

--------------------------------------------------------------------------------
Note on RAh, RAm, RAs, DE-, DEd, DEm, DEs:
The position is truncated from NPM2 Catalog -- it is meant for ID only
Note on ID: the values are:
0= ID acceptable, no comment
1= ID confirmed from good/fair finding chart, variability, or proper motion
2= ID may be doubtful, star may have footnote in npm2foot.dat (see code IN)
3= ID probably or certainly incorrect (from post-reduction check)
Note on IQ: the values are:
0= acceptable, no comment
1= weak (faint) or oversize (bright) image (poor measures)
2= near-blend: neighboring star, grating image, film defect,
elongated image, or reseau cross on first-epoch blue plate
3= reject image (survey code error, wrong exposure system, blank field, etc)
Reject list: NPM2+62.1518, NPM2+60.0713, NPM2+07.1658,
NPM2+05.2146, NPM2-22.1382
Note on REFc: the conventions are:
0000 = No chart used
D0000 = Durchmusterung chart
G0000 = Guide Star Catalog
nnnn = Usually the same as r_Star, except for variable stars
(see file "npm2cros.txt")
Vnnn = Variable star catalog chart number nnn in
REFc=0001,0614,0615,0616,0971,0972,0973,1003
(see file "npm2cros.txt")
Note on n_mag: the codes are:
0= none
1= V
2= B
3= mpv (or visual estimate, other yellow measures)
4= mpg (mb and similar blue measures)
5= red (near-ir, others of uncertain type)
6= Cousins magnitudes (Rc,Ic),
7= Hipparcos Hp and/or Tycho-2 BT (rarely used)
8= JHKVLM near-ir bands (rarely used)

Note on sim: the codes for comparison with SIMBAD nomenclature are:
' '= "PUB" reference is found in SIMBAD
