Abstract

With this paper we begin to present a photoelectric realization of the sofar photographically defined RGU-system.

The data reduction technique is based on Rufener's method of variable principal extinction coefficients, which is applied to the photoelectric RGU-system to determine accurate extraterrestrial G-magnitudes and (G-R) and (U-G)-colors of a first set of standard stars.
