Stokes I (black contours) and polarised intensity (colour scale) image of NRAO 150 at 22 GHz. The contour levels at 0.25, 0.5, 1, 2, 4, 8, 16, 32, and 64% of the total intensity peak (S_max = 2.5 Jy beam⁻¹). The lowest contour cutoff is at 6 σ_I, with σ_I = 0.4 Jy beam⁻¹. The green ellipse in the bottom left corner denotes the convolving beam size of (0.20 × 0.35) mas with a semi-major axis at a position angle of 10.9° north to east. The green bar (bottom right) corresponds to a (projected) distance of 8000 R_S (4 pc). The polarised intensity cutoff is at 6 σ_P. The dotted box corresponds to the optically thin, downstream jet region used to align the EVPAs to the bulk jet flow. The white bars show the orientation of the EVPAs with the calculated correction of Δχ_turn ∼ 93°. The orange line denotes the ridge line.
