Maps of the parameters (offset, amplitude, period, and phase) of the sinusoidal functions obtained for the red region of Fig. 7. Top row: quantities characterizing the sinusoidal time-evolution of the radiative losses, while the second row represents the quantities characterizing the time-evolution of v_LOS at cmass = −3.8. In the maps of the period, yellow contours indicate the plage area corresponding to Q < −20 kW m⁻² (see Fig. 7). The first column from the right shows the phase difference between Q and v_LOS. Bottom row: quantities of the sinusoidal evolution for v_turb at cmass = −3.8.
