Time sequence of inversion maps of Event A from combining Ca II 8542 Å and Ca II K. From left to right the columns show temperature (left-most three columns), temperature difference with the input model (middle three columns), and line-of-sight velocity (right-most three columns) at the log τ₅₀₀ heights specified in the first row panels. The time in UT is indicated in the top-left corner of the first panel of each row. The panels have been byte-scaled by column (ranges indicated by the colour bars at the top of each column). The dashed lines in rows 5, 8, and 9 indicate the lines along which Fig. 9 shows cross-cut inversion maps.
