Table 1 Per-line average relative error for the methods evaluated in this paper.

Per-line average relative error for the methods evaluated in this paper.. We provide summary statistics for different models for all lines, where the values are percentages of the average relative error defined in the “Data setup and evaluation criteria” section in Results. The top part of the table indicates results averaged over the entire test set, whereas for the bottom part only data points where the Fe XX line is in the 95th percentile are kept, to focus on flare conditions. Numbers in bold indicate the best result within the given column.
