Topto bottom: Column density per velocity channel of ArH⁺, p-H₂O⁺, o-H₂O⁺, OH⁺, and CH towards G10.472+00.027. The blue shaded region represents the uncertainties while the pink dashed line, and shaded region mark the systemic velocity of the source and highlight the velocity dispersion of the source. The dashed blue lines indicate those velocity intervals that were omitted from the fitting routine due to contamination.
