Radiation parameters for the disk in RX J1604 in the fractional polarization vs. scattered intensity I_disk/I_* plot. The gray data points show the J band and H band values and the dotted gray line the locations defined by Q_ϕ/I_* for the R band. Open points show results for transition disk models for i = 7.5° from Ma & Schmid (2022). The red point is the reference model with the parameters, X_r, given in Table 5, while the open points show models with one model parameter, X_r−1 or X_r+1, deviating from the reference case (values increase along the dashed arrows). The color coding is given in the inset.
