Introduction
A general outline that covers the steps necessary to fit a RHESSI Spectra, starting with the creation of the RHESSI Spectrum file and going through the process of defining background, time intervals, and fitting models to the data using OSPEX.

Create a spectrum file using the HESSI GUI
Starting with the level zero RHESSI data this document goes through the steps necessary to create a spectrum file using the HESSI GUI:
Creating a spectrum file with the HESSI GUI
This includes the details of creating a file for a single detector using the GUI as well as simple command line instructions for accomplishing the same. The end result is a spectrum and spectrum response matrix (SRM) file in the .fits format which can be read by OSPEX.
Fitting a time interval using the OSPEX GUI
The following document gives a step by step example of using the OSPEX GUI to fit a time interval:
Users Guide for the OSPEX GUI
This includes defining background, setting up time intervals, choosing a fit model and doing a fit for a single interval.
Vth
This document contains a brief explanation and example of how to use the variable thermal model component:
How to use Vth
The variable thermal component uses a single emission measure and temperature along with the relative abundance of the Fe-Ni complex to model the thermal portion of the RHESSI spectrum as a function of energy for a user defined time interval.
Bpow
This document contains a brief description of how to use the broken power law component:
How to use Bpow
The broken power law component is a single power law which uses a break energy, the power law index above the break energy and below, and a count rate dependent normalization to model the non-thermal component of the RHESSI spectrum as a function of energy for a user defined time interval.
