Fig. 1


Bolometric correction factor as a function of the source intensity (open circles). Filled circles show the dependence of the ratio of the total flux in 0.5–10 keV plus 15–50 keV to the 0.5–10 keV flux as a tracer of the bolometric correction factor (Kbol). Red crosses show the Kbol value and the source flux (in 0.5–10 keV range) from the broadband spectra collected with the NuSTAR observatory.

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.
