Activity-rotation relation using the generalised Rossby scaling from Reiners et al. (2014) for (upper left panel) L_X /L_bol and (upper right panel) normalised Hα luminosity. The lower left plot shows the correlation of L_X/L_bol and normalised Hα luminosity and the lower right plots shows the correlation of L_X/L_bol with v sini, where only detectable vsini values are shown and the number of points not plotted is shown. For Hα inactive stars, the value of L_Hα∕L_bol where the numbers are placed in the figures are at the L_Hα∕L_bol values that correspond to the detection limit of pEW(Hα) = −0.5Å.
