Radiation parameters for the 0.5-model as functions of disk inclination i. Panel a: disk integrated intensity , azimuthal polarization intensity , and Stokes Q-intensity expressed relative to the stellar intensity. Panel b: disk-averaged fractional polarization 〈p_φ(i)〉 and 〈p_Q(i)〉 of the scattered radiation, and the maximum fractional azimuthal polarization measured in the disk image max (p_φ(i, x, y)). Panel c: Quadrant polarization parameters Q_xxx/I_⋆, U_xxx/I_⋆+ relative to stellar intensity.
