(2010a) using Lbol = 33L2−10 keV, (Col. 7) best fit for SMF0, (Col. 8) parameter varying in SMF1, with the percentage of variation, (Col. 9) parameter varying in SMF2, with the percentage of variation, (Col. 10) the sampling timescale, and (Col. 11) variations in the hardness ratios.
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.
