Notes. The Tau 042021 fluxes represent the total flux from both the western and eastern lobes of the disk. The data are primarily taken from Table 1 of Arulanantham et al. (2024), with the S(9) flux adopted from Pascucci et al. (2025). Note that the spatial integration areas are larger in our model than in the Tau 042021 observations, so direct quantitative comparisons should be made with caution (see Section 4.4.1 for details). The SY Cha fluxes are adopted from Schwarz et al. (2025a), measured with a radius aperture of 0.5-2.0" (note that d = 180.7 pc).
