5.3.11 Parameter restoringbeam

The restoringbeam parameter allows the user to set a specific Gaussian restoring beam to make the final restored .image from the final .model and residuals.

If restoringbeam=’’ (the default), then the restoring beam is calculated by fitting to the PSF (e.g. the .psf image). For a mosaic, this is at the center of the field closest to the phasecenter.

To specify a restoring beam, provide restoringbeam a list of [bmaj, bmin, bpa] which are the parameters of an elliptical Gaussian. The default units are in arc-seconds for bmaj, bmin components and degrees for the bpa component.

For example,
