- This burst occurred during the period of recovering the thermal control system (Barthelmy et al., GCN Circ. 18562). The CZT bias voltage has been reduced to -150v (instead of the normal -200v) and as such the energy scale in the data from the Quicklook and HEASARC sites is somewhat off from the proper calibration. Therefore, an accurate spectral analysis is unavailable. # single-ish pulse GRB.
