Time sequence of aftermath image cutouts as in Fig. 2. Columns: Hα Dopplergrams at Δλ = ± 0.6 Å with black denoting redshift. Hα images at line center, Ca II 8542 Å Dopplergrams at Δλ = ± 0.3 Å, Ca II 8542 Å images at line center. The first two rows are for the same moments as the last two rows in Fig. 2 and share their numbers. The intensity images are bytescaled individually but the Dopplergrams have identical greyscales along columns.
