Notes. $^{(a)}$~This column gives the model orientation, measured East of North. For the BINARY~model, $\phi$ gives the PA of the separation vector, while for the SKEWED RING, VERTICAL RIM, and CURVED RIM~models, the orientation of the ellipse/rim major axis is given. Due to a lack of closure phase calibration observations on the E0-G0-H0 array configuration, we are unfortunately not able to unambiguously define the CP~sign, resulting in a~180$\deg$-ambiguity in the derived position angles.
$^{(b)}$~In the fitting process, this parameter was fixed. 
$^{(c)}$~This model is point-symmetric, resulting in a CP which is identical zero.
