Analysis Summary
Notes:
- 1) No attempt has been made to eliminate the non-significant decimal places.
- 2) This batgrbproduct analysis is done using the HEASARC data.
- 3) This batgrbproduct analysis is using the flight position for the mask-weighting calculation.
Special note: This burst was outside the BAT calibrated field of view (the FLUX mask region)
in the whole event data range (see figure below),
hence spectral analysis is not available.
