Flare Modeling Software
This page provides links to software for computing the x-ray, gamma-ray, and radio emissions from solar flare models. The numerical codes are packaged with documentation in html (*.html, *.htm), Adobe Acrobat 4.0 (*.pdf), and/or Microsoft Word (*.doc) format. Sample input and output data are also included for testing the codes. IDL routines (*.pro) for graphically displaying the output are included in most cases.Most of the numerical codes will run and have been tested on a Pentium III PC equipped with a compiler such as Compaq Visual Fortran and 128 MB of memory. The graphics routines will run on a PC equipped with IDL version 5.3 or later.
The codes are open and can be freely modified by the user. This open-code policy has been adopted to maximize the use of HESSI data and to open the physical interpretation of the HESSI data to as broad a community as possible. Please remember, however, that the developers of these codes put many hours of labor into them, and are most knowledgeable about the strengths and limitations of the codes.
These codes should always be properly cited when used to obtain results for publication. We strongly recommend that such work be done in collaboration with the code developers. Although the codes have been tested, the correctness of the numerical results is not guaranteed and all results should be thoroughly scrutinized. We ask that any errors or significant improvements to the codes be reported to the developers for inclusion in future releases.
Links to numerical programs are provided below. Additional programs will be added as they become available. A program that computes images and spectra of the x-ray and microwave emissions from specific flare models is currently under development. This will be made available here, and compiled versions will be made available in the HESSI branch of the SolarSoftWare tree.
The Numerical Codes
For each code the program name links to the online documentation. To download the code, documentation, and accompanying files to a Windows PC, click on the name of the Zip file or on the link to the program files. Download to an empty file folder, and unzip any downloaded *.zip files to extract the compressed files.
