Observations of right ascensions of selected FK4stars concerning themagnitude equation.
Abstract
Reduced observational materials on 141 stars are presented which were used to investigate the possibility of a magnitude equation in the northern declination zone between 30 and 60 degrees of the FK4 catalog. Results are reported for the index number, FK4 number, magnitude, spectral type, number of observations per star, mean right ascension and mean declination, mean epoch of observations, mean residuals, and mean square error of residuals. The stepwise multiple regression procedure used on the data base is discussed. No magnitude equation for the stars was detected.
