Herschel/PACS 70 μm, 100 μm, and 160 μm false-colour composite image of U Cam (left), ST Cam (middle), and VY Uma (right). Spatial scales are indicated with the horizontal bar. The compass is oriented with galactic coordinates and the arms are 1′ in length (we note that the images have been rotated to align the symmetry axis for each object). The PACS beam sizes (FWHM) at 70 μm, 100 μm, and 160 μm, are represented by the small blue, green, and red circles in the upper right corner of each panel.
