Tueller (GSFC), \non behalf of the Swift BAT team:\n\nGRB 041223 (Tueller et al., GCN #2898) was a spectrally hard burst.\nFits to the total Swift-BAT burst spectrum are consistent with a power\nlaw, with a photon index of 1.05-1.15.\n\nThe BAT team did not quote a total band fluence in GCN 2898, due to\nuncertainty in the response at high energies.  Now, with further\nsimulations and spectral analysis, we estimate that the 15-350 keV\nfluence was ~5E-5 erg/cm^2.  The peak flux was 3E-6 erg/cm^2/s (15-350\nkeV; 1 s sampling), which is dominated by the highest energy band.",
