Density plots of the Hα (top two rows) and Ca II K (bottom two rows) spectra for RBE and RRE/downflowing RRE RPs (0–7). The density (darker meaning higher concentration of spectra) corresponding to each RPs shows the distribution of profiles over the whole time series. The solid lines overplotted correspond to the RPs discussed in the text. The blue (red) color coding indicates the excursions in the blue ward (red ward) side of Hα respectively.
