Angular momentum in the y-direction versus z-direction (top) and energy versus angular momentum in z-direction for PDR1 6D giants. Sagittarius stream is seen as a clear overdensity in negative y-direction angular momentum and is separated using a simple L_y cut. These Sagittarius stream stars are shown in orange in both the panels. The same cut is used in PGS 6D giants to isolate Sagittarius stream members but the number of member stars are significantly lower.
