Mean atmospheric stratifications obtained from the inversion of the selected pixels in the Hinode/SP normal map (Fig. 3). The first and second rows represent the results for blue and red events, respectively. Color coding follows this designation. The first column displays the temperature T, second column the LOS velocity v_LOS with positive values representing downflows, third column the magnetic field intensity B, and fourth column the inclination of the magnetic field γ. Gray areas indicate the deviation from the mean stratifications obtained from the 358 pixels belonging to blue events and 158 pixels belonging to red events (see Sect. 3.1).
