SO line temperature ratio TR(SO 1011−1010)/TR(SO 98−87) versus intrinsic line temperature TR(SO 98−87) predicted by RADEX slab models at TK = 50, 500 K (black and red points/curves). Each curve corresponds to the labelled column density NSO/ ΔV increasing from 1012 to 1015 cm-2 (km s-1)-1 by factors of 10 (left to right). Each dot along the curves corresponds to the labelled log(nH2) (from 105 to 107 cm-3). Optically thin models are marked with a cross, and optically thick models with a star. The black points indicate the upper limit of the SO line ratio and the SO 98−87 intensity corrected for beam dilution in the B2, B3, and R2 knots over the HVjet velocity range.
