Similar to Fig. 4, for ratios of AIA and Hi-C[CB] intensities averaged over several sub-regions of the Hi-C field of view. The field of interest (FOI; top) and the field of view (FOV; bottom) are split into 3 ×   3 equal-area square grids and the pixel-wise ratios of the light curve intensities are averaged over each cell of the grid are shown. Each curve is marked with a colour and symbol corresponding to the cell in the grid as shown in the grid key at top right. In all cases the 1σ standard errors are marked with thin vertical lines. The black dashed line in the bottom plot shows the average of the ratios over the full Hi-C FOV. For comparison, the ratio averaged over the entire FOI from Fig. 4 is shown in the top plot as the grey shaded region.
