Illustration of the normalized total flux F_I (top), the percentage F_Q∕F_I, and the polarization P for inclinations of 10, 50, 90, 130, and 170 deg. The electron-density enhancement is characterized by V_blob = 4000 km s⁻¹, δV_blob = 400 km s⁻¹, and N_e,fac = 20; the blob radial electron-scattering optical depth is 0.098 and the blob opening angle is 20 deg. To reduce the strength of the narrow spikes in the polarization and to mimic the approximate resolution of typical spectropolarimetry data, the model has been smoothed with a Gaussian kernel (FWHM of 23.5 Å).
