Update: Jean explained the difference between his plots and mine. The catalog pipeline limits the spectral index of the PL fit to the flux-in-band data to 0<Γ<5. This is done to avoid arbitrarily large indexes in the case of exponential cutoffs. I'll replot the data tomorrow.
This page describes my efforts to draw flux-in-band spectral plots for 2FGL sources that have curved spectral models (in particular the super exponential). For curved spectra, I have been unable to reproduce the plots that Jean posted. In particular I concentrate on the plot for PSR J0007+7307 / 2FGL J0007.0+7303.
