Photon flux spectra (black), model fit (Fe and Fe–Ni lines: olive; super-hot: brown; hot: magenta; non-thermal: green; total model: blue), and normalized residuals during the RHESSI SXR peak of the flare on 2002-Jul-23 at ∼00:31:30 UT, when the super-hot component is strongest. Inset: 50% and 90% contours of 6.3–7.3 (olive solid), 9–12 (blue dotted), 17–18 (brown dashed), and 60–100 keV (green dot-dashed) images at the same time; the crosses denote the derived centroid locations (and uncertainties) of the super-hot (brown; left) and hot (magenta; right) components.
