Notes. (1) Location; (2) name of the surface brightness cut; (3) distance of the maximum deficit to the central bin (red vertical line in Fig. 4); (4) length of the cavity along the radio axis; (5) width of the cavities perpendicular to the radio axis; (6) width of the shocked region perpendicular to the radio axis; (7–8) surface brightness value at the maximum deficit and at the location mirrored about the radio axis; (9) maximum surface brightness deficit; (10) average apparent emissivity at the location mirrored about the radio axis of the maximum deficit; (11) depth (that is, the width along the line of sight) of the cavity. The uncertainties for lengths are estimated as the bin width.
