Correlating std(RV) of the active RV-loud stars with three of their spectral parameters – left: v sin i; middle: SpT; and right: log L_Hα∕L_bol. The points are color-coded according to SpT in all three plots, from M0 in blue to M9 in red. Correlation significances, as measured by the p(F_test) values, are shown in the insets. A log(p-value) < −2.3 means a significant correlation, while a log(p-value) between − 1.3 and − 2.3 means a marginal correlation.
