GALAXY RED-SHIFTS BY PHOTOELECTRIC SPECTROPHOTOMETRY.

Abstract

Preliminary report on experiments to replace the classical photographic technique by photoelectric spectrophotometry in measuring radial velocities of galaxies. Examples of velocities measured in 1965 with a medium-dispersion spectrum scanner attached to the 82-inch reflector of McDonald Observatory are discussed. (Author)
