Thermal flare parameters plotted versus cotemporal energy input rate by nonthermal electrons, P_nth. Shown are temperatures T (top), emission measure increase rates dEM/ dt (middle), and thermal energy increase rate dE_th/ dt (bottom), derived from RHESSI (left column) and GOES data (right column). Also shown are power-law fits (full lines), the slope and intercept of the obtained power law, α and b, and the rank correlation coefficient, R. For T, an exponential fit (dashed gray line) is also shown together with the fit parameters γ and d. For dE_th/ dt, the dotted line denotes x = y, and the median ratio M of the thermal energy increase and the nonthermal input is indicated.
