Properties related to the crossings of the SFMS compared to M_★, for the three groups of galaxies considered: ALL (black), MS (blue), and RET (red). Top: Distribution of the galaxies in M_★. Second pane: Average number of crossings (𝒞_SFMS) for each M_★. Third panel: ΔSFR in dex after a crossing has happened. Fourth pane: Average interval (ΔAge) between crossings for the galaxies, in Myr. For the bottom three panels, the shaded areas correspond to the error of the mean.
