Soft band 0.3 − 3 keV ACIS-S flux image smoothed with a Gaussian kernel with a 5 × 5 pixel () σ, with superimposed the regions used for spectral extraction. The cyan lines (full for the cross-cone directions and dashed for the N and S directions) represent the cones in which the soft X-ray emission extends with a signal-to-noise ratio of at least 3 (see Fig. 6). The green lines represent the contour level at 30 times the rms level for the 150 MHz (see Fig. 3) maps. The magenta xs represent the detected X-ray sources, excluded from the spectral extraction.
