Maps of the main parameters of the two thermal components: temperature, ionisation time, and normalisation. The normalisation is the volume emission measure as defined by VNEI model divided by the region area. The top row corresponds to the VNEI 1 associated with the IMEs, the bottom one is the hotter VNEI 2 related to the iron-rich ejecta. The scales are not the same in both rows. The value in the upper-left of each map indicates the mean uncertainty (the median of the uncertainties over all regions)
