Simulated focal plane image for the full, 20 arcmin, field-of-view. Each spot is shown for the two extreme positions of the roof mirror, i.e. green (0 mm) and blue (90 mm). The black circles represent the airy disks. It is clear that the “walking” of the beam is well contained in the diffraction disk.
