Scientific paper

A photoelectric radial-velocity spectrometer has been constructed for the coude spectrograph of the 1.2-m telescope at the Dominion Astrophysical Observatory. The design of this instrument is discussed, including an innovation which eliminates the problem of 'mismatch' for observations of high-velocity stars. Performance of the instrument is discussed, and results are given of a comparison of the spectrometer velocity system with the systems of IAU, LICK, Griffin, and Beavers and Eitter.
