 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,
