Welcome to Fermi Gamma-ray Data Tools Documentation!¶
The Fermi Gamma-ray Data Tools (GDT) is a toolkit for Fermi data built on the GDT Core Package and is the next iteration of the Fermi GBM Data Tools.
The Fermi Gamma-ray Space Telescope was launched on June 11, 2008 and contains two intruments: the Large Area Telescope (LAT) surveying the sky in the ~20 MeV–300 GeV energy range, and the Gamma-ray Burst Monitor (GBM) observing the full unocculted sky with 14 individual detectors from ~8 keV–40 MeV. Currently the toolkit services all Fermi GBM public data, and a future version will incorporate support for some Fermi LAT data.
Citing
If you use the Fermi Gamma-ray Data Tools in your research and publications, we would definitely appreciate an appropriate acknowledgment and citation! We suggest the following BibTex:
@misc{GDT-Fermi,
