Notes. TS is the Test Statistic and Nsrc is the number of events attributed to the source model. k0 is given in units of 10−11 ph cm−2 s−1 TeV−1, Ec in units of TeV and β is dimensionless.
Values are from Aharonian et al. (2006a) for their dataset III which covers the period during which the observations of the H.E.S.S. public data release were taken.
Values are from Nigro et al. (2019). “n.c.” signals that the information was not communicated in the publications.
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.
