Left : Herschel/PACS images of VYUMa. The solid cyan represents the aperture used to isolate the central component (representing the present-day mass-loss), and the dashed cyan lines the aperture used to measure the extended detached shell. Right : Radial surface brightness profiles, the markers indicate the surface brightness from the images, the dashed line the surface brightness from DUSTY models convolved with their respective Herschel/PACS PSFs, and the dotted lines the Herschel/PACS PSFs.
