Same models as in Fig. 13, but now showing the evolution of the normalized total flux F_I and scaled, blueshifted polarized flux |F_Q| in the Hα region (zero Doppler velocity corresponds to the line rest wavelength) as a function of the inclination (progressing clockwise from 10 to 90 deg; the value of the inclination is given at the top left of each panel). The flux F_Q,1−blob corresponds to the single-blob case in which a blob is placed along the symmetry axis and the computation is done over 180 deg in latitudes (no mirror symmetry). In contrast, the flux F_Q,2−blob corresponds to the case in which a blob is placed along the symmetry axis but the simulation is carried over from 0 to 90 deg in latitude and assuming mirror symmetry – this is then equivalent to having two blobs180 deg apart. The value of the blueshift is the same for each polarized flux and set to − V_blob(1 − cosα_los), where α_los is the inclination of the single blob in the 1-blob case, and of the approaching blob in the 2-blob case. We use the same scaling of |F_Q| for both models, so that the difference in polarization level between the two models is preserved (the continuum polarization in the 8000 Å region is given at the top left of each panel, below the value of the inclination). The enhancement is characterized in all cases by V_blob = 4000 km s⁻¹, δV_blob = 1000 km s⁻¹, β = 10 deg, and N_e,fac = 20, corresponding to a radial blob optical depth of 0.436.
