Herschel PACS images of HIP 22263, HIP 62207, and HIP 72848 (left to right) at 70, 100 and 160 μm (top to bottom). Contours are at increments of 3-, 5-, 10- and 30σ from the image background level. Colour scale is linear from the background to source peak brightness. Orientation is north up, east left. Pixel scales are 1′′ per pixel at 70 and 100 μm, and 2′′ per pixel at 160 μm. The PACS beam size in each band is represented by the circle in the bottom left corner of the images in the left hand column.
