Evolution of the Hα velocity offset with time. The graph is color coded for Bowen N III TDEs (blue) and not Bowen (orange). The embedded panel contains the Hα offset of the first available epoch of each TDE. The Hα line at the first epoch for the majority of the TDEs is blueshifted. The N III Bowen TDEs show lower offsets compared to the rest of the TDEs which show more extreme values.
