Radial profiles of surface brightness at (top to bottom) 70, 100, and 160 μm: (left) along the long axis and (right) along the short axis. The coloured shaded areas mark the uncertainty, while symbols represent the two respective directions along each axis. In the lower-left of each panel, the stellar contribution is plotted. Azimuthally averaged radial profiles of Wiener deconvolved and deprojected images are given as solid line, and their azimuthal standard deviations are represented as dotted lines, both in arbitrary units.
