2) The analysis was also done with two different time windows to try and get a statistical check on any of the features observed in the SEDs for the full timeframe.

Between 100MeV and 1GeV there appears to be significant variation in the flux observed by the Fermi satellite depending on which type of events (Front, back, or both) are used in producing the SEDs. The SEDs, using close to three years of observation data, are as follows:
Full time window MET Start = 239557417 seconds (2008-08-04T15:43:37) Stop = 328855431 seconds (2011-06-04T04:43:49) | Back only events
