Abstract:
We have conducted a radial-velocity survey of bright (V<9),
overluminous, F stars within 80pc. Of the total of 118 stars
selected, the radial velocities of 77 have been measured with
the Cambridge CORAVEL in the present survey.
Description:
Radial-velocity observations for our survey have been made with a
spectrometer at the coude focus of the Cambridge (UK) 36 inch
reflecting telescope.

Note (1): Flags have the following meaning:
1 = The star was on R.F. Griffin's observing program before the current
survey began.
2 = R.F. Griffin had already published the orbit of the star.
3 = The star was observed as a part of this survey, but its orbit has
already been published in a separate paper.
4 = An orbit had already been published by others.
5 = Not observed because previous observations by others indicate
constant radial velocity.
6 = The star was already asserted in the literature to be a binary,
but no orbit had been determined.
Note (2): C (constant) indicates nondetection of radial-velocity variations
Note (3): Except where uncertainty is indicated by a colon, the
formal errors of rotational velocities are ≲1km/s
Note (4): the brightness anomaly represents the difference in the absolute
magnitudes computed from the trigonometric parallaxes and from the
Stromgren photometry.
