Extended Data Fig. 5: Velocity dispersion profile for DLA0817g.

Extended Data Fig. 5

The observed velocity dispersion profile is measured from the standard deviation of a Gaussian fit to each pixel, and is shown by the data points where the data have been binned into bins equal to the size of the horizontal error bars. The vertical error bars reflect the 16 to 84 percentile spread in measurements per bin. The radius has been de-projected for the inclination of DLA0817g. The dashed line is the value derived from the kinematic modelling. The solid coloured region is the 16 to 84 percentile spread in the constant velocity dispersion model, showing that the increase in velocity dispersion at the galactic centre is due to beam-smearing.
