Average R_per (two first lines) and rms of individual R_per (two last lines) over each time series vs. B−V (left) and Log (right). Firstand third lines correspond to ΔTspot₁, and second and fourth lines to ΔTspot₂. The color-coding corresponds to the inclination, from pole-on (i = 0°, yellow) to edge-on (i = 90°, blue), with light and dark orange corresponding to 20° and 30°, light and dark red to 40° and 50°, brown to 60°, and light and dark green to 70° and 80°. Only one simulation out of five is plotted for clarity.
