Doppler dimming effect displayed at time steps 189 and 192 when the prominence erupts. The POS results are shown in the first and third rows while the LOS integrated results are shown in the second and fourth rows. The radiative component without and with Doppler dimming, as well as the extent of dimming are shown in the first three columns. The collisional component is present in the fourth column for comparison and the ratio of the two components is displayed in the last column. The black dashed boxes give the region where the PRODOP calculation is done for the eruptive phase.
