Notes.

NH, Gal is the column density of the Galactic absorption; EBr is the break energy in the bknpower component; Γ1 and Γ2 are the photon indices at lower and higher energies compared to EBr, respectively; kT is the temperature in the bbody model; Tin is the temperature of the inner region of the accretion disk in the diskbb model; Γ is the photon index in the powerlaw model; Γhot and CFhot are the power-law photon index and covering fraction for the hot corona, respectively, modelled with the thcomp model; Γwarm and CFwarm are for the warm corona; kTe is the electron temperature of the warm corona; fsoft, diskbb, fsoft, bb, fsoft, po are the intrinsic flux calculated over the rest-frame 0.2 − 2.0 keV band for the diskbb, bbody, and powerlaw model, respectively; fsoft is the total intrinsic 0.2 − 2.0 keV flux. X2 was taken at the end of the PX, rise phase. X3 and X4 were taken during the PX, plat phase.

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.
