TL;DR: The IGRB spectrum shows a significant high-energy cutoff feature, and can be well described over nearly four decades in energy by a power law with exponential cutoff having a spectral index of $2.32\pm0.02$ and a break energy of $(279\pm52)$ GeV using our baseline diffuse Galactic emission model as mentioned in this paper.

TL;DR: In this article, the authors describe the development of the Galactic Interstellar Emission Model (GIEM) which is the standard adopted by the LAT Collaboration and is publicly available, based on a linear combination of maps for interstellar gas column density in Galactocentric annuli and for the inverse-Compton emission produced in the Galaxy.
