  Table I gives the ﬂuxes and signiﬁcances averaged 
  over all the days from Aug. 12, 2008 (the beginning of 
  science operations) to Dec. 15, 2009, approximately 
  490 days. 
  
  The results presented here are preliminary. We 
  have not completed the ﬁne tuning of our algorithms, 
  though the average ﬂuxes are not expected to change 
  much. Future work will 
  include using the GBM 
  CSPEC data, with its ﬁner energy binning, to exam- 
  ine the detailed spectra for these sources. 
  
  The Crab (Fig. 2) spectrum in the hard x-ray/low 
  energy gamma-ray region can be described by a bro- 
  ken power law, with the spectrum steepening at 100 
  keV and then hardening at 650 keV [7, 8]. While the 
  GBM CTIME data do not have the spectral resolution  The measured 20 - 50 keV GBM light curves are 
  compared to Swift’s 15 - 50 keV light curves for sev-
