  The information given above comes from the quick-look analysis performed
  daily on data obtained from the Burst and Transient Source Experiment (BATSE).
  The typical sensitivity of these measurements using the Earth occultation
  technique (one-day integration) is ~100 mCrab. Be aware that sources within
  about 22 degrees of the orbital poles are not occulted by the Earth;
  therefore, some bright sources may not show up in the daily averages.

  These quick-look science results are freely available, but should be 
  considered preliminary.  Please use with caution.  For additional information,
  contact B.A. Harmon (harmon@sslmor.msfc.nasa.gov).
