Table 1
Kinematical, physical, and dynamical properties of the jet from DG Tau B in the high- and the low-velocity components (HVC and LVC, respectively) averaged over the first 5′′ of the red and the blue lobe.

Notes. The values of Vrad and ΔV are derived from Gaussian fits to the [Sii]λ6731 line profiles and to the Hαλ6563 (in parentheses).
