The inset in the PSF image (when present) corresponds to the central 41 pixels of the PSF.
When the beam shape is significantly non-Gaussian, the dotted contour of the 50% level
of the PSF image will become distinctly visible apart from the fitted synthesized beam,
which is shown as the solid contour.
