(Q/I) of the Cr i triplet computed with CRD (solid line), R_II (dotted line), and a combination of CRD and R_II (dashed line) for μ = 0.15. The positive Q represents linear polarization parallel to the solar limb. The thin solid line in Q/I at the 0.025% level represents the continuum polarization. The microturbulent magnetic field B_turb = 0. No spectral smearing is applied to the profiles in panel a). In the line core the Q/I profiles computed with pure R_II and with a combination of R_II and CRD nearly coincide (see the insets in panel a)). Panel b) shows a comparison between the Q/I profiles computed with CRD and with R_II when we also apply a spectral smearing of 80 mÅ. The line types have the same meanings as in panel a).
