From top to bottom: a) jet radius, r_jet, in arcseconds (as estimated by Mundt et al. (1991) for distances larger than  ~2′′ and  ~3.5′′ in the blue and red lobe, respectively, and by Stapelfeldt et al. (1997) for lower distances); (b), c)) mass flux rate, Ṁ_jet, in units of 10^-9M_⊙ yr^-1, and flux of linear momentum, Ṗ_jet, in units of 10^-6M_⊙ yr^-1 km s^-1, estimated in the high- (HVC, red points) and low- (LVC, black points) velocity components.
