Fig. A.2

Results for the same Monte Carlo simulation as in Fig. A.1 (for the radiative-transfer disk with i = 60°), but with a temperature-gradient model that also includes the inclination i and the position angle PA as free parameters. Clearly, neither the half-light radius, nor i and PA are well constrained. The radiative-transfer disk has cosi = 0.5 (i.e., i = 60°) and PA = 0°/ 180°.
