List of Functions Available in OSPEX for RHESSI Spectral Fitting
Introduction
This page lists the fit function components the user may select when doing a RHESSI spectral fit. The are chosen from the drop down menu at the top of the 'Choose Fit Function Components and Set Parameters' GUI:
A simple tutorial on fitting a time interval using OSPEX can be found in OSPEX Documentation.
