As in Fig. 5, but showing the relation between thermal parameters derived from cotemporal RHESSI and GOES data for three different evolutionary stages of the flares. Compared are the emission measures (left column) and temperatures (middle column). Additionally, the corresponding thermal volumes are compared to the volume at the GOES SXR flux peak, V_th,peak (right column). The three evolutionary stages correspond to the times of the maximum RHESSI temperature (top row), the SXR peak (middle row), and the latest analyzed time interval (t = t_end; bottom row). RHESSI gives lower emission measures and higher temperatures than GOES in the early flare phase, when the thermal volumes are comparatively large.
