Distribution of projected rotational velocities (v sin i) for the two samples identified in the main sequence (left panel). Right: sHRD (ℒ ≡ ) for the total sample, with v sin i average in each bin, and overlaid on the rotating evolutionary tracks from Köhler et al. (2015). Each hexabin shows the mean value of all stars within it.
