Maximum gravitational energy, E_grav (top) and maximum kinetic flow energy, E_flow (bottom) of the hot plasma plotted versus maximum thermal energy, E_th, derived from RHESSI (left) and GOES data (right). Power-law fits (full lines), the slope α and intercept b of the obtained power law, and the rank correlation coefficient R are also indicated. The dotted line denotes x = y, and the median ratio M of the different energies is indicated. Both gravitational and flow energies are significantly lower than the maximum thermal energies.
