LOS-integrated results of Fig. 2 are displayed from top to bottom: I_rad, I_coll, I_total and the ratio of I_coll and I_rad are shown from left to right. The observable structures of prominence, cavity, central cavity and horn are marked in the panel of total emission at time step 165. The white dashed box gives the region where the PRODOP calculation is done for the static stage. The contours, the line curves and the vertical lines are indicated as in Fig. 2.
