Upper panel: ΔRV_obs versus the amplitude of the Log , on averaged time series (see text), in black. ΔRV_conv is shown in red. Lower panel: same as the upper panel. Red vertical lines correspond to the ΔRV_conv reconstructed for inclinations of the rotational axis in the range 10–90°. The green circle is the solar value (seen equator-on), and the green line indicates what the solar value would be for various inclinations. The orange dashed line corresponds to ΔRV_conv reconstructed from Eq. (5) for T_eff between 4950 K (lower curve) and 6150 K (higher curve) with a step of 200 K between each curve.
