Left: Chandra residual map after subtracting a spherically symmetric double beta model fit to the surface brightness profile of Nest. A depression near the C1 lobe can be seen in the image and has been highlighted as a circular region. A further possible depression may be present near the C2 lobe. The image has been heavily Gaussian-smoothed with a σ = 30″ and r = 30″ for better visualization. Right: XMM-Newton exposure-corrected image showing the region around the C1 lobe. The image has been Gaussian-smoothed with a σ = 6″ and r = 12″ for better visualization. A possible limb-brightened feature around the C1 lobe is shown in the figure as a wedge. The LOFAR radio contours from Figure 2 are shown in green. The X-ray center of the group has been marked with a cross in each figure. The different lobes have also been marked on each figure.
