Spectral line and temperature profiles for six selected pixels in Events A (top and bottom two rows) and B (second row) at the identically coloured locations marked in Fig. A.1. The left-hand, middle, and bottom panels show fits assuming hydrogen ionisation in LTE (dashed lines) and non-LTE (solid lines) to the observed profiles (filled circles) for Ca II K (left panel in the first three rows), Ca II 8542 Å (middle panel in the same rows), and Mg II (bottom panel). The corresponding temperature stratification (right-hand panels) is shown using the same colour coding, along with the FAL-C input temperature for reference (dashed black line).
