Notes. Total count rate in energy bands F and D, the number of working PCUs and the hardness ratio h = ND/ (NFND) are shown, along with non-linear dynamics indicator in energy bands F and D, obtained for Nϵ different values of recurrence threshold ϵ and the time bin dt, with uncertainty σ. The recurrence analysis was done for a continuous part of the observation consisting of N = 32 768 points. The exceptions are the following:

(a)

N = 16 507,

(b)

N = 21 437,

(c)

N = 27 439.

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.
