Results for the two-component model corresponding to the best-fit parameters listed in Fig. 7. Panel a shows the total normalized flux (solid lines), the mean value for the constant component (I_c, 1 = I_c, 2 = 0.23, horizontal dashed lines), and the flux of the variable component accounting for the uncertainty in the constant component (crosses). Panels b and c show the observed Stokes parameters normalized to the average flux (crosses) and the best-fit model (dotted lines). Panels d and e show the PD and PA for constant (horizontal dashed lines) and variable (crosses) components, respectively. The solid line in panel e matches the solid set of lines in Fig. 3e with the constant component subtracted. Red and blue symbols and lines correspond to Obs. 1 and Obs. 2, respectively.
