Notes. Name of the 66 long GRBs (upper part) and 4 short GRBs (lower part) in our sample are reported in the first column. Time interval adopted for the spectral analysis (with respect to the LAT trigger time), spectral index (α_LLE), normalization, and corresponding PG-Stat and DOF values. Errors are given at 90% level. The spectral analysis is conducted in the 30 – 100 MeV range. For GRBs 090227B, 120226A, 130504C, 131216A, 140102A, 150403A and 150523A, the lower energy bound is extended to 10 MeV.

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.
