Notes. (a) Beam-averaged CO, SO, and SiO column densities in the jet (NCO, NSO, NSiO) are derived from the CO, SO, and SiO line intensity integrated on the high-velocity range at the position of the blue-shifted and red-shifted SiO emission knots closest to the driving sources, B and R (see Table 4 and the spectra in Fig. C.1). We assume LTE, optically thin emission at TK = 100 K. The lower and upper limits reported in the table refer to the cases where the CO (2− 1) and/or SiO (5− 4) emission is (or could be) optically thick based on the 
/
ratio (see Sect. 4.4). (b)The abundances of SO and SiO are derived as XSO = XCO × NSO /NCO and XSiO = XCO × NSiO /NCO assuming 
.
(c) Mass-loss and momentum rates (Ṁjet, Ṗjet), and the jet mechanical luminosity (Ljet) are derived from NCO assuming Vjet = 100 km s−1.
