Notes. Column 1: source ID; Col. 2: fitting model in the 0.5–7. keV rest-frame band: baseline (absorbed power law and a gaussian), E free (baseline with Energy of gaussian free), mek (baseline+mekal) to account for the soft excess, pex (baseline+pexrav), pex E free (baseline+pex with centroid of the gaussian free), pow: baseline+pow to account for the soft excess; Col. 3: column density of local absorber in 1022 cm-2; Col. 4: photon index of the observed power law; Col. 5: EW of the narrow Fe line at 6.4 keV expressed in eV; Col. 6: temperature of material emitting the mekal component (mek); Col. 6 represents the centroid energy of the iron line when left free and the reflection fraction of the Compton reflection when added; Col. 7: chi square/d.o.f.; Col. 8: linear correlation coefficients obtained with the least-squares regression between photon index and the flux (obtained from the spectral fits of the six epochs in the band between 0.5–7. keV); Col. 9: p-value for the least-squares regressions reported in Col. 8: these represent the probability that the two parameters are not correlated. In Cols. 8 and 9, the least-squares regressions have not been computed for source 382 (because it has only the spectra of two epochs).
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.
