Radial profiles of the turbulent width in m s-1, top row, and as a function of local sound speed, bottom row. The blue dots show the results of the direct method, where the CO and CN lines were assumed to be fully thermalised, and CS to be co-spatial with CN to derive a Tkin value. Yellow solid lines show the results from the global fit where the total line width was fit for, while dashed grey lines show the global fit where vturb was fit for individually. The 1σ uncertainties are shown as bars for the direct method and as shaded regions for the lines. A representative error associated with the flux calibration of 7% at 80 au is shown in the top left corner of all panels.
