Notes. The epoch number is given in the first column and the corresponding date in the second. Other columns present the results of the analysis: TS, differential flux at the decorrelation energy, the spectral index Γ, the decorrelation energy, and integrated flux between 100 MeV and 500 GeV.
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.
