Top: height of HXR emission at the lowest (red vertical lines) and highest (blue vertical lines) imaged energies, EUV emission at different wavelengths (see legend), and WL relative enhancement where the black line indicates the height of maximum enhancement. Arrows indicate the corresponding uncertainties. Middle: energy deposition rate as a function of height for two different cases of electron cutoff energy. Bottom: fitted density model (thick solid line). The thin solid lines give the lower and higher limits of the density determined by the uncertainty in the fit of the scale height. The model from Vernazza et al. (1981) is given for comparison.
