Example mG-ring model. The model consists of an m-ring of diameter d, with azimuthal variations determined by Fourier coefficients β m and with thickness determined by convolution with a circular Gaussian of FWHM W. The mG-ring model also includes a circular Gaussian of FWHM W Gauss and fractional relative flux density f Gauss (Equation (20)). The position angle η of the ring is determined by the phase of the m = 1 mode (Equation (23)), while the magnitude of its asymmetry A is determined by the amplitude of the m = 1 mode (Equation (24)). The red curve in the middle panel shows a radial profile in the horizontal direction; the orange curve in the bottom panel shows the azimuthal profile and its decomposition into its three modes. The plotted model has w = 0.3, f Gauss = 0.2, W Gauss/d = 0.8,β 1 = − 0.3i, and β 2 = 0.1 + 0.1i.
