Comparison of the heliocentric radial velocities measured with the 2.3m/WiFeS spectrograph to the ones published by Gaia DR3. Most of the Gaia DR3 errors are smaller than the dots. The error on the WiFeS RV was estimated to be ~20 km s−1. The distribution of differences between both measurements is shown in the bottom right figure. The red line of slope one is used for visual guidance only.
