See example-ebtel-hxr.pro for a demonstration of the reworking/streamlining of the codes to calculate expected HXR fluxes from EBTEL nanoflare simulations.
The code expects that you have the EBTEL code available. EBTEL can be obtained from https://github.com/rice-solar-physics/EBTEL. All other needed procedures are in the PRO directory.
The MPFIT directory contains the files used for automated optimization of parameters. This is under development.
