P_rot (from McQuillan et al. 2014), R_per, and fraction of missing stars vs. T_eff. Upper panel: the two red curves indicate our lower and upper boundaries in P_rot. The red dotsindicate stars within this P_rot range and green dots indicate stars within this P_rot range and R_per above 8000 ppm. Middle panel: only stars within our P_rot range for each spectral type are shown. The red (resp. green) points represent the median R_per from our simulations vs. T_eff, for ΔTspot₁ (resp. ΔTspot₂). The orange line is the median of the observed values within each bin. Lower panel: only stars within our P_rot range for each spectral type are shown.
