Scientific paper

An analysis is conducted of radial velocities measured on 51 spectrograms of 14 late type standard stars at a dispersion of 12.4 A/mm. A list of 15 suitable lines and wavelengths for radial velocity determination in late type spectra is established, by means of which the internal and external standard errors for a single plate are found to be 0.25 and 0.66 km/sec. The present velocity system is in good agreement with the standard system, but the results obtained for HD 51250 agree better with the revised velocity proposed by Batten (1982). The variability of the former IAU standard stars HD 35410 and HD 80170 is confirmed.
