is in au. The disk has a total flux, $F_{tot}$, at 1.3 mm, and its mid-plane is assumed to incline by an angle of $i$ from face-on (i.e., $i=0$) with the major axis along a position angle (P.A.). There are three parameters describing the bright source: the total flux ($F_{pt}$) and offset from the star ($\Delta x$ and $\Delta
y$). We discuss the results in the following subsections for both approaches, and synthesize the final best-fit model parameters in Section 3.4.
