Notes. Columns are as follows: (1) Annulus ID. (2) and (3) inner and outer radius, in arcmin. (4) Number of bins in each annulus (note that a total of 504 of bins are included in the annuli). (5) Number of 2σ outliers after combining neighbouring bins. (6) and (7) mean and median surface brightness in 0.5–3 keV, in units of 10−10 photon cm−2 s−1 arcsec−2. (8) Fisher-Pearson coefficient of skewness; (9) Emissivity bias defined as bx = SBmean/SBmedian. (10)(11)(12)(13) are measurements with the 16 clump candidates removed.
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.
