Kolmogorov–Smirnov test

Variable	Test statistic	p-value
Statistically significant

U (LSR)	0.569	1.00e-267
Guiding radius	0.317	9.22e-79
zmax	0.175	4.21e-24
V (LSR)	0.126	1.24e-12
[α/Fe]	0.107	2.53e-09
ecc	0.077	5.53e-05
[Mg/Ce]	0.068	5.52e-04

Statistically insignificant

Notes. Velocity components U(LSR), V(LSR), and W(LSR) are in the Local Standard of Rest. Other variables, including guiding radius, maximum vertical height (zmax), and eccentricity (ecc), are from Galpy. Abundance ratios are from APOGEE DR17.
