Photometry of faint red stars
Broadband photoelectric BVI photometry has been obtained for 56 redstars detected in an objective-prism survey. The magnitude range for theprogram stars was V = 8.6-12.2. The sample contained 33 probable dwarfstars and 21 probable giant stars identified using the (B-V) - (V-I)two-color diagram and two stars of uncertain luminosity class. Distanceswere derived from photometric parallaxes and used with proper motionsobtained from various sources to compute tangential velocities for theprobable dwarf stars.

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.
