Notes. (a) RA and Dec offset of the innermost SiO knots B and R. (b)Distance of the innermost SiO knots B and R. (c)High-velocity range (HV) where CO (2−1) and SO (56−45) trace jet emission as SiO (5−4). (d) Jet radial velocity in the innermost SiO knots B and R estimated as the velocity of the SiO emission peak in the B and R spectra with respect to the source systemic velocity given in Table 1. The estimated jet radial velocities are affected by an uncertainty of ± 1.7 km s−1 due to the resolution of our spectra. (e)Ratio between the radial velocities, Vrad, of the blue- and red-shifted innermost knots, B and R. The ratio is computed between the velocity of the faster knot, Vrad, f, over the velocity of the slower knot, Vrad, s. (f) CO (2− 1), SO (56 − 45), and SiO (5− 4) line intensity integrated on the high-velocity range (HV) (FCO, FSO, FSiO).
