Illustration for the same model as in Figs. 5–6, but now showing the evolution of the scaled total flux F_I (black) and the polarized flux |F_Q| (red; scaled and blue shifted) versus Doppler velocity (zero velocity corresponds to the rest wavelength of Hα). Nine different inclinations, increasing from left to right and from top to bottom, are shown. The blueshift was applied to the polarized spectra to compensate for the redshift induced by scattering in a blob moving radially at 4000 km s⁻¹, and its numerical value is indicated in the top right corner of each panel. It corresponds to − 4000 (1 − cosα_los) km s⁻¹, where the inclination angle α_los is indicated in the top left corner of each panel. The percentage value in the upper left corner of each panel corresponds to the polarization in the relatively line-free region around 8000 Å.
