text: eral sources over the same time intervals in ref. [2], 
  where it is seen that the results measured by the two 
  instruments compare well. At energies above the up- 
  per energy limit of ∼ 195 keV of the Swift 22-month 
  catalog [6], however, the GBM observations provide 
  the only wide-ﬁeld monitor available of the low en- 
  ergy gamma ray sky. 
  
  This work uses the GBM CTIME data, with its 
  8 broad energy channels and 0.256-second resolution, 
  rebinned to 2-second resolution. The occultation tech- 
  nique relies on an input catalog of known sources. 
  Currently, we are monitoring 64 sources. Of these 
  64 sources, 6 steady sources are detected above 100 
  keV with a signiﬁcance of at least 5σ after ∼ 490 days 
  of observations, and one transient source. 
  
  A. Steady Sources 
  
  The sources Crab, Cyg X-1, Swift J1753.5-0127, 1E 
  1740-29, Cen A, and GRS 1915+105 are detected by 
  GBM at energies above 100 keV. We show GBM light 
  curves generated from the Earth occultation analysis 
  in several energy bands with one day resolution for 
  these six sources in Figures 2 - 7.
