Demonstrating uncertainties in the DEM results using the degradation-corrected AARP data set to reconstruct temperature, as compared to using the uncorrected JSOC downloaded image files (“ground truth”). Left: 171 Å image for context; middle: ﹩\mathrm{log}({T}_{\mathrm{ÅRP}}/{T}_{\mathrm{JSOC}})﹩ map showing spatial differences between the two; right: correlation plot between T _AARP and T _JSOC in log scale. The gray line shows the 1:1 correspondence line.
