Atmospheric profiles for the clusters with high emission in the blue wing of the representative profiles. The columns are split into the two different simulations (left: simulation A, right: simulation B). Top row: Average spectra of the clusters. Bottom three rows: Average atmospheric quantities in the clusters. From the top, they are the gas temperature, line-of-sight velocity, and total dissipative heating (Q_viscous + Q_joule). The dashed black lines show the averages for the entire simulations. The distribution in the bottom row is the column mass of the blue emission clusters where τ_ν equals unity for the inner blue wing (−5.4 km s⁻¹) of Ca II H.
