Notes. In the column names, the band flags indicate a few energy bands as listed in Table. A.2. The suffix flags in the flux-related columns (FluxObsv, FluxCorr, FluxIntr, LumiIntr) include ‘Med’ (posterior median), ‘Lo1’, ‘Lo2’ (1σ/2σ percentile lower limit), ‘Up1’, ‘Up2’ (1σ/2σ percentile upper limit), and ‘BF’ (best-fit). For other X-ray spectral parameters, the suffix flags include ‘Med’ (posterior median), ‘Mean’ (posterior mean), ‘Std’ (standard deviation), ‘Lo’ (1σ lower limit), ‘Up’ (1σ upper limit). For a few spectral shape parameters, for example, Γ and NH , we also provide ‘HLo’ (1σ HDI lower limit), ‘HUp’ (1σ HDI upper limit), and ‘KL’ (KL divergence). These X-ray spectral parameters are named and calculated in the same way as described in Liu et al. (2022b).
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.
