\caption{Moments of the \ensuremath{v\sin i}~distributions for each spectral
  subsample. "total'' corresponds to the whole subsample (including CP and CB~stars);  "normal'', CP and CB~stars are also distinguished. For both "total'' and "normal'' subsamples, the moments are given for different groups of luminosity class: all (IV, IV--V, V), V and~IV (class~IV--V luminosity stars only are not considered because they represent a~very small fraction of the sample). The number of stars~(\#), the center and the dispersion of the distribution are given. Centers are estimated using the median and the mean, and the dispersion is evaluated with the standard deviation.}
