The Spectroscopic Absolute Magnitudes and Parallaxes of 4179 Stars

The methods described in previous publications have been used for determining stellar absolute magnitudes by the spectroscopic method. A larger number of lines has been used (Table I) and the reduction-curves have been revised. The catalogue gives the spectral type, absolute magnitude, and parallax determined for 4179 stars mostly of types later than A5 and north of declination - 26°
