Stokes profiles for the core and near-wing region of the K line for a LOS with μ = 0.1: I/I_cont (first panel), Q/I (second panel), U/I (third panel), and V/I (fourth panel). The curves represent the emergent profiles considering uniform and vertical magnetic fields with different strengths, indicated in the legend. The reference direction for positive Stokes Q is the parallel to the nearest limb.
