Two-dimensional cut through the loop plane. Panels a) and b) show the density and temperaure at a snapshot at the same time as Figs. 1 to 5. Overplotted are the magnetic field lines (dashed) defining the magnetic loop, which roughly coincides with the plasma loop defined by the density structure. Panel c) displays the heating rate per particle averaged over 10 min before the time of the other snapshots. This also roughly coincides with the magnetic loop. Panel d) shows the synthesized emission in the AIA 171 Å channel defining the eLoop outlining the EUV emission. This is smaller than the magnetic loop and the plasma loop and has roughly constant width. The lines labeled [a] and [b] indicate the cuts shown in Fig. 7.
