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 data are of a preliminary nature and should only be used for planning observational programs, and are not intended for publication. Please do not distribute this report beyond your local team.
