(a) Light curves of HRIEUV and five EUV channels of AIA with intensities averaged over the E₁₀ event region. The time interval when the EIS slit passes over the event is delimited by two blue vertical lines. (b) DEM of the event E₁₀, along with the background regions 1 and 2. The ratios of the reconstructed radiance over the observed one is plotted on the effective temperature of each line.
