Notes. The fluence is from fitting the spectrum with a Comptonized function over a combined (NaI and BGO detectors) spectral range of 8 keV–40 MeV.
( † )Includes the saturated portion of the spectrum from about T0 − 2.4 to −0.8 ms.
( * )Includes the data gap, from about T0 + 4.6 to 6.6 ms.
( † †)This does not include the correction for the brightest part of the event that was saturated in Fermi/GBM as in Roberts et al. (2021), which accounts for the lower values in this study.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
