Notes. The datasets in the first/last rows are prior/subsequent to the MAGIC observations and are reported for comparison. For each dataset the following quantities are reported: the MJD time of the beginning of the observations; the exposure time; the integral flux in the 2 − 10 keV band; the a and b parameters for the log parabola fit (or the photon index Γ in case a simple power-law is used, see text); the reduced χ2 with number of degrees of freedom nd.o.f.. PL indicates when the simple power law is used instead of the log parabola.
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.
