Position–velocity diagram of the ¹²CO(1-0) (left panels) and ¹²CO(2-1) (right panels) emission along the major axis of the molecular gas disk (top panels) and AGN-jet line (bottom panels) of 3C 293. Positions (Δz′) are relative to the AGN. Velocities are relative to the . The contour levels are − 3σ, 3σ, to 36σ in steps of 3σ for the ¹²CO(1-0) diagrams and − 3σ, 3σ to 12σ in steps of 3σ for the ¹²CO(2-1) diagrams. 1σ = 0.9 and 1.7 mJy beam^-1 for the ¹²CO(1-0) and ¹²CO(2-1) diagrams, respectively.
