Sample 2D Gaussian plus point-source model fit to the observed V2 and closure phase data for NGC 3783 from Jan 7, 2018. The best-fitting Gaussian FWHM geometric mean size of ≃0.6 mas is consistent with that found from 1D Gaussian fitting (GC20b). The Gaussian PA and point source flux fraction and offset are consistent with those found from image reconstruction.
