Analysis forTrigger 209351

Analysis Summary

Notes:

1) No attempt has been made to eliminate the non-significant decimal places.
2) This is a special analysis for ground-detected GRB. The event data duration is likely to be shorter than the burst duration. In such cases, the burst durations are found using the quad-rate data, and spectral analyses are only available for event data range.
3) Some mask-weighted light curve plots might be missing because the time range is not completely covered by the event data range.

Special note: This burst was outside the BAT calibrated field of view (the FLUX mask region) until 168939832.544000 s (T0+23.7 s). Therefore, the whole T100 range (~ T0-6.75 s to ~ T0+16.75 s) was outside of the calibrated field of view, see figure below. The spectral analysis is thus unavailable, and the rest of the analyses use the DETECTION mask.

Lightcurves

Notes:

1) The mask-weighted lightcurves have units of either count/det or counts/sec/det, where a det is 0.4 x 0.4 = 0.16 sq cm.
2) The verticle lines correspond to following: green dotted lines are T50 interval, black dotted lines are T90 interval, blue solid line(s) is a spacecraft slew start time, and orange solid line(s) is a spacecraft slew end time (for the best duration plot, slew times are marked by green arrows).
3) For lightcurves in unit of count rate, time of each bin is in the middle of the bin.
