PACS images, isocontours, and SEDs of α Men/HIP 29271 (left), HD 88230/HIP 49908 (middle), and HD 210277/HIP 109378 (right). Images: 100 μm (left), 160 μm (right). North is up and east to the left. Isocontours: 100 μm contours are in green, while the 160 μm ones are in red. α Men: 100 μm contours (10, 20, 40, 80, 90% of the flux peak); 160 μm contours (20, 40, 60, 80, 90% of the flux peak) HD 88230: 100 μm contours (10, 20, 30, 40, 60, 80, 90% of the flux peak); 160 μm contours (20, 30, 40, 50, 60, 80, 90% of the flux peak) HD 210277: 100 μm contours (30, 40, 50, 60, 70, 80, 90% of the flux peak); 160 μm contours (50, 60, 70, 80, 90% of the flux peak). The lowest contour in all cases is  ≈ 3σ. The optical position of the stars are indicated by the symbol “*” in the isocontour plots; a segment indicates the projected linear sizes at the distance of each star. SED plots: black line is the photospheric fit while the blue line is the photosphere plus a 22 K black body.
