Notes. p1 is the proton spectral index
before the break, p2 is the proton spectral index
above the break, is the
proton break energy, is the
proton cut-off energy, Kp and Ke are
proton and electron normalization constants, and
is the reduced chi-square.
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.
