Comparison between line-of-sight velocity templates derived in this work (top panels, based on APOGEE and Gaia data) and those derived in previous studies (bottom panels, together with APOGEE line-of-sight velocity template). For each line-of-sight velocity template derived in this work, we also included a shaded region (in top and bottom panels) depicting the measured scatter along the template (see Tables A.3 and A.5).
