Abstract:
This catalogue lists the spectral classifications of over 3200 stars,
mainly of large proper motion, observed and classified by the late Dr.
G.P. Kuiper during the years 1937-1944 at the Yerkes and McDonald
Observatories. While Kuiper himself published many of his types, and
while improved classifications are now available for many of these
stars, much of value remains: for a great many of the objects no other
spectral data exist.

Global Notes;
Note (G1): When no passband specified, photoelectric V magnitude is given,
largely taken from the extensive compilation by Jaschek et al. 1972
(Ser. Astr. La Plata Obs. 38), but includes many from other sources.
Magnitudes originally within brackets like (10.1) were replaced with
colon-flagged magnitudes, e.g. (10.12) was replaced by 10.12:.
The passbands may be:
v = visual or photovisual magnitudes taken from Kuiper's original file
cards. For many of the fainter stars these are no doubt eye estimates
at the telescope.
p = photographic
U B V R = ultra-violet, blue, visible or red magnitudes
For variable stars, magnitude data are taken from the GCVS and its
supplements.
Note (G2):
Luminosity classes were not usually given by Kuiper. The letter "f"
following a spectral type indicates that the lines appeared weak.
The colon (:) indicates an uncertain spectral type, and the double
colon (::) a very uncertain type.

History:
* Catalogue received at CDS in October 1987
* 20-Aug-1996; standardized at ADC by Julie Anne Watko
-- addstars.dat : aligned columns;
-- lttstars.dat : records combined for the triples LTT 4763 and 6409
-- online documentation standardized.
* 16-Apr-2016: magnitudes standardized at CDS by Francois Ochsenbein:
A dedicated column for the band-pass and the uncertainty flags were
added. Also fixed error of declination sign in addstars.dat, rec#104.
Accurate positions and identifications of the stars have been added
in the files "lttstars.pos"and "addstars.pos".
