Radial intensity profiles in the three PACS band (70, 100, and 160 μm from left to right). The observed profiles are presented by black dots, while colour curves represent the best fit model profiles according to Eq. (1) (see Table 2). The corresponding radial intensity profiles of the respective PACS PSFs are shown as dashed curves.

This figure is made of several images, please see below:
