FIRST RADIAL-VELOCITIES FOR 146 BRIGHT F-TYPE AND G-TYPE STARS

We have obtained an average of 5.7 radial velocities for 146 northern stars of types F and G (all luminosity classes) listed in ''A Supplement to the Bright Star Catalogue'' as having no previously known radial velocity measures. Those were obtained with CCDs and a cross-correlation technique; the intrinsic velocity accuracy, based on stars of apparently constant velocity, is probably less than +/-0.3 km s(-1) per mean. Of those stars 14% are newly discovered SB2 stars. The prevalence of rapid line profile variations (in minutes or hours) in most of the broad-lined F-type stars makes it difficult to obtain accurate measures for them.
