Orbital elements of six spectroscopic binary stars.

Orbital elements of the spectroscopic binary stars, HD 1273, 148704, 167954, 194215, 202940 and 217792 are presented. HD 148704 shows double lines on a few plates and a somewhat uncertain mass ratio is determined. For HD 217792 elements have been previously published by Buscombe and Morris. The present solution uses a period almost exactly half theirs. The method described in the Appendix has been used to investigate thoroughly large ranges of trial periods and to eliminate some alternative cases, including, in the case cited, the period adopted by Buscombe and Morris.
