Comparison between the P_rot values adopted in this work (from K2 or TESS) and those published by Hartman et al. (2010). The color of symbols distinguishes the three subsamples as indicated in the legend. The one-to-one relation is shown by the black dashed line. The green and purple dotted lines with slopes of 0.5 and 2, respectively, are also shown. The most discrepant stars are enclosed into squares in blue (for P_rot reported in Rebull et al. 2016) and red (for P_rot values derived in this work from TESS data).
