Results of RHESSI spectral fitting during 09:00:20−09:00:40 UT. The data points with horizontal and vertical error bars represent the observed data. The spectra for thermal and nonthermal component are plotted with red and blue dashed lines, respectively. The sum of two components is shown with a magenta dashed line. The fitted parameters, including the thermal temperature (T), emission measure (EM), electron spectral index (δ), and low-energy cutoff (E_c), are labeled.
