Comparison of EM results with X-ray data for the 2013 December 10 flare. (a). X-ray light curves in 1–8 Å calculated from AIA EM maps and observed by GOES. A background selected at ∼06:30 UT is subtracted from the GOES fluxes. (b). An example of T_EM maps in the rising phase (marked in panel a). (c). De-convolved “Al_thick” image observed at ∼07:19:49 UT by Hinode/XRT. (d). Predicted “Al_thick” image from AIA EM maps. The XRT temperature response function used here was multiplied by a factor of 2, as suggested by Wright et al. (2017).
