This work is the second part of the set of measurements of v \sin i for A-type stars , begun by Royer et al . ( 2002 ) . Spectra of 249 B8 to F2-type stars brighter than V = 7 have been collected at Observatoire de Haute-Provence ( OHP ) . Fourier transforms of several line profiles in the range 4200–4600 Å are used to derive v \sin i from the frequency of the first zero . Statistical analysis of the sample indicates that measurement error mainly depends on v \sin i and this relative error of the rotational velocity is found to be about 5 % on average . The systematic shift with respect to standard values from Slettebak et al . ( 1975 ) , previously found in the first paper , is here confirmed . Comparisons with data from the literature agree with our findings : v \sin i values from Slettebak et al . are underestimated and the relation between both scales follows a linear law v \sin i _ { \mathrm { new } } = 1.03 v \sin i _ { \mathrm { old } } +7.7 . Finally , these data are combined with those from the previous paper ( Royer et al . 2002 ) , together with the catalogue of Abt & Morrell ( 1995 ) . The resulting sample includes some 2150 stars with homogenized rotational velocities .
