The spatial location of the APOGEE stars included in this study are shown. The grid indicates the spatial division of stars we used to seek for high-VGSR (∣VGSR∣ ∼ 200 km s−1) peaks. The increase in spectroscopic spatial coverage due to APOGEE DR16 is apparent; in particular, the bulge at negative longitudes can now been explored. Our new AAT observations are shown at (l,b) = (−6,0), as well as the globular cluster stars included in our analysis.
