Comparison between Gaia-determined systemic velocities (Clementini et al. 2023) and our determined υ_sys using newly derived line-of-sight velocity templates and scaling relations. The top panel shows a zoom-in of the stars with the difference between Gaia and our values below |20| km s⁻¹, while the bottom panel shows the entire scale. The numbers in each panel denote the total number of stars displayed in a given plot.
