Notes. (a) The
20% systematic error on the observed integral flux above 240 GeV is not
shown. (b) The Crab
nebula flux percentage is
calculated relative to the HESS value above 240 GeV (Aharonian et al. 2006c).
(c) The ,
degrees of freedom (NDF), and corresponding
probability P(
)
are given for fits of a constant to I(>240
GeV) binned nightly within a dark period, or monthly within a year, or
yearly within the total.
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.
