Spectroscopic binary orbits from photoelectric radial velocities. Paper 71: HD 17198

An accident of misidentification has brought to light an interesting object whose listed spectral type of A0 is by far the earliest to be measured with the radial-velocity spectrometer. Probably the system actually has a composite spectrum and includes a late-type giant which is the object to which the radial velocities really refer. The orbit is highly eccentric and has a period of 675 days. The mass function is very large and implies a substantial prospect of eclipses, the next of which would occur about 1988 February 5.
