Abstract:
Rotational velocity vsini and mean radial velocity are presented for a
sample of 232 Ib supergiant stars covering the spectral region F, G
and K. This work is the second part of the large survey carried out
with the CORAVEL spectrometer to establish the behavior of the
rotation for stars evolving off the main sequence (De Medeiros &
Mayor, 1999, Cat. J/A+AS/139/433). These data will add constraints
to the study of the rotational behavior in evolved stars, as well as
solid information concerning tidal interactions in binary systems and
on the link between rotation, chemical abundance and activity in stars
of intermediate masses.
Description:
The observations are from De Medeiros & Mayor, 1999, Cat.
J/A+AS/139/433. The large majority of the observations were carried
out from March 1986 to May 1994, except for those stars having a
larger time base. All stars north of declination -25° were
observed with the CORAVEL mounted on the Swiss 1-meter telescope at
the Haute-Provence Observatory, Saint-Michel (France). The stars south
of declination -25° have been measured with the southern CORAVEL
at the Cassegrain focus of the 1.5m Danish telescope at ESO La Silla
(Chile).

Note (1): In this case the uncertainty is given by
max(ε1/sqrt(N), σ/sqrt(N)), where
ε1 is the typical error for one single radial velocity measurement.
Note (2): The remarks SBO, SB and SB? indicate:
SBO: single-lined spectroscopic binaries for which the orbital
parameters are available in the literature,
SB: stars presenting a single-lined spectroscopic binary behavior on
the basis of CORAVEL observations
SB?: the stars with a trend towards a single-lined spectroscopic
binary behavior based on CORAVEL observations.
