Notes.
The fit of the Fourier transform of point source in the uv-plane has 3 free parameters: the source RA and Dec positions relative to the phase centre and its flux. Fitting a Gaussian distribution has additional parameters: the width (HPW) for circular Gaussian (C-GAUSS) and the major and minor axis for an elliptical Gaussian (E-GAUSS), as well as its orientation with respect to the north (position angle PA).
This value has been derived after subtracting the contribution of the free-free emission (see text, Sect. 5.3).
