Surface brightness radial profiles through the center of the halo along the nebular major axis (﹩\mathrm{P.A.}\,=15^{\circ }{\mbox{--}} 25^{\circ }﹩; top) and the equator (﹩\mathrm{P.A.}\,=105^{\circ }{\mbox{--}} 115^{\circ }﹩; bottom) of the ﹩K_{p}﹩ (black), ﹩L_{p}﹩ (blue), and ﹩M_{s}﹩ (pink) images. Cuts are shifted by an arbitrary amount in the relative intensity axis for clarity. Thick (thin) lines are used for the NE (SW) lobe. Radial power laws ∝﹩r^{-4}﹩ and ∝﹩r^{-3}﹩ are shown for comparison (dotted lines).
