Notes. The following columns report (1) the observation ID; (2) the observation time; (3) the exposure of analysed observations; (4) the integrated flux in the energy range from 2 to 10 keV; (5) the photon index for the power law fit to the spectrum; (6) the reduced χ2 and the number of degrees of freedom for the power-law fit. The given F2−10 keV fluxes are not corrected for Galactic absorption, since in energy band of 2−10 keV this effect is found to be negligible.
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.
