In the 3PC, Fermi-LAT collaboration tried to fit a SuperExpCutoffPowerLaw4FGLDR3SpectralModel with the exponential index index_2 free, or fixed to 2/3. These two models are referred as “b free” and “b 23”. For most pulsars, both models are available. However, in some cases the “b free” model did not fit correctly.

Parameters:

fitstr, optional: Which fitted model to return. The user can choose between “auto”, “b free” and “b 23”. “auto” will always try to return the “b free” first and fall back to the “b 23” fit if “b free” is not available. Default is “auto”.
