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).
