Collimation of the DG Tau B redshifted outflows. The orange dots show the derived positions of the H₂ edges from the NIRSpec map. The red filled area indicates the full jet opening angle and the red dots trace the jet axis positions both derived from the F164N NIRCam image. The filled blue conical area show the projected outlines of the outer and inner limits derived by DV22 for the bright conical CO outflow. The light blue areas below ∼180 au correspond to the extrapolated CO flow edges, where no measurements are available. All error bars are 3σ. The double yellow arrow shows the thickness of the H₂ cavity estimated in Sect. 3.1.1.
