A photometric study of K and M dwarf stars found by Stephenson
Broadband photometry has been obtained for a sample of the K and M dwarfstars found in an objective prism survey by Stephenson (1986). Among thestars with unknown proper motion, about 24 percent of those observedappear from the photometry not to be dwarfs, although the percentagevaries considerably with spectral type. For stars with V less than 11.5and B - V equal to or greater than 1.2, it is estimated that, within thearea surveyed, Stephenson's survey is about 68 percent complete.

Dwarf K and M stars of small proper motion found in a large spectroscopic survey
More than 2000 candidates for K and M dwarf status, generally havingproper motions that are either unknown or less than 0.2 arcsec perannum, have been identified in an objective-prism survey covering theentire sky north of declination - 25 degrees and more than 10 degreesfrom the galactic plane. More than 95 percent have no previousindication that they are dwarfs. Several dozen appear to be visualdouble stars.
