Rotational velocity $v\sin i$ and mean radial velocity are presented for a sample of 231 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). 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.

Key words: stars: supergiant -- stars: late-type -- stars: rotation -- techniques: radial velocities -- catalogs
