For off-zenith imaging, it is more accurate to fit a Gaussian to the PSF as to what WSClean currently does.

    There's now a new parameter '-fitbeam' which performs a least-squares minimalization between a 3-parameter Gaussian (sigma x, sigma y, correlation). When -fitbeam is specified, the beam is subsequently restored with an elliptical Gaussian with the found parameters.

    For now, I have not made this the default -- will probably do so in version 1.6.
