Fermi Gamma-ray Space Telescope

User Contributions

The FSSC welcomes contributions to the Fermi Science Tools from the scientific community. If you have developed an extension to the science tools or any other tool useful for Fermi data analysis, please let us know and we will post it on this website. While the FSSC will work with the developer to resolve any issues with the software the contribution is provided "as is" and may not work after a software or data upgrade (e.g. to pass 8 data), updating the tool or script remains the responsibility of the developer. For the moment, please direct any communication to the Help Desk.
