GOES light curves (top), temporal evolution of temperature (middle panel), and emission measure (bottom) calculated based on GOES fluxes. The values related with observations from GOES are plotted as dashed lines, and solid lines represent the values as obtained based on GOES fluxes synthesised using the numerical 1D-HD model. Red and blue colours in the top panel correspond to the GOES 0.5–4 Å and 1–8 Å channels. The orange dots represent the average temperature (T_a, middle panel) and total emission measure (EM_tot, bottom) values calculated based on the DEM distributions from RESIK data.
