Abstract

Projected rotational velocities are presented for 178 bright dwarf stars () with spectral types in the range A8 till G2. These rotational velocities have been determined by Fourier-Bessel transformation of the line profiles of six Fe i absorption lines in a 50 Å  wide range centered on 6250 Å. Rotational velocities of stars with suspected velocities of more than 40 km/s were also determined by fitting the whole spectral range with a profile of a slowly rotating star of the same spectral type that has been convolved with a rotation profile. The agreement between the results obtained with these two methods is very good.
