Left panel: soft band 0.3 − 3 keV ACIS-S flux image smoothed with a Gaussian kernel with a 5 × 5 pixel () σ, with the angular sectors used for the azimuthal profile extraction superimposed in green. Right panel: black points indicate the surface flux profile in the 0.3 − 3 keV band extracted in the sectors shown in the left panel; the vertical black bars indicate the uncertainties on the surface flux and the horizontal black bars indicate the bin widths. The full black line represents the best-fit model, comprising two Gaussians plus a constant to account for the background level, for the profile; the blue shaded areas represent the regions chosen for the N and S cone regions, that is, the angles comprised between two standard deviations from each Gaussian peak.
