Selected quantities along a cut through a FS indicated in Figure 5. Top panel: Temperature (black) and density (blue). Middle panel: Vertical magnetic field (black) and vertical velocity (blue, negative values denote downflows). Bottom panel: δE^{1D − 3D} (black) and continuum intensity, I_c (blue). All the quantities were taken at a geometrical height of z = 0 km. The vertical dotted lines indicate the boundary region of the flux element over which the density decreases and the magnetic field increases.
