Dependence of the synthetic Stokes Q and U maps on the orientation angles. The maps shown corresponds to the Allen et al. (2003a,b) model with H₀ = 0.125, v₀ = 0 and t = 2 × 10⁴ yr. Thick contours: correspond to a single combination of position and inclination angle. Individual panels: inside thick contours two panels are shown. Stokes Q and U map are shown in the left- and right-hand side panels, respectively. Common color scale for each Stokes map is shown below the first column. The angular scale is shown in the bottom right-hand side panel. Map contours: represent steps of 3-σ starting at 3-σ, where σ = 2.5 mJy beam^-1. Columns: correspond to a position angle, φ, shown on the top. Rows: correspond to an inclination angle, ω, shown on the left-hand side of the figure.
