Position velocity (pV) diagrams (continuum subtracted) for IRAS 17208-0014 where the y-axis shows the position along the major axis (position angle 90°) and the x-axis shows the radial velocity relative to the cz of 17208–0014 km s^-1. Upper panel: HCN 4–3. Centre panel: H₂S Lower panel: HCO⁺ 4–3 blended with HCN-VIB. Colour ranges from 2 to 70 mJy, contour levels are 5 × (1,3,5,...17) mJy beam^-1. The vertical dashed line marks z = 0.04271 the suggested redshift by Garcia-Burillo et al. (2015), while zero velocity marks the redshift z = 0.04281. The horizontal white bar indicates the nuclear position of the HCN-VIB line.
