Averaged spectra measured toward the blue lobe of outflow A for species CO, ¹³CO, HNC and SiO. The spectra are measured within the outer contour of the integrated intensity maps from Fig. 2 for each species. The vertical dashed line gives the V_lsr of the target and the vertical dotted lines mark the range in velocity from Table 2, based on which the integrated intensity maps were produced as were the CO outflow property calculations. The chosen limits are described in the main text.
