Two different geometries for the interpretation of the blueshifted absorption troughs in the Fe K band of PG 1126-041. A wind with a smaller R_in (corresponding to υ_∞ = −0.25c) and observed at a larger inclination angle (θ = 80°) is shown in blue, while a wind with a larger R_in (corresponding to υ_∞ = −0.0625c) observed at a smaller inclination angle (θ = 65°) is shown in red. Top panel: sketch of the geometry of the disk wind in the two cases (only R_in has been sketched for simplicity), with streamlines represented by arrows with different thicknesses, proportional to the terminal velocity. Central panel: two theoretical models. Bottom panel: 2009 pn data (in gray) overplotted on the two models folded with the instrumental response.
