Notes. 

(a)

Energy conversion factor to convert the F band count rate into 0.5–10 keV flux assuming an absorbed power-law spectrum with hydrogen column density NH and photon index Γ;

(b)

same as a, but to convert the S band count rate into the 0.5–2 keV flux;

(c)

same as a, but to convert the H band count rate into the 2–10 keV flux.

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.
