Kinematic ratio A/σ₀ for all generated mock GC systems in the halo of Aq-A, regardless of viewing angle. The dashed histogram shows the subsample of systems that have similar azimuthal distributions to the halo GC system of M 31 (see text for details). The solid and dashed vertical lines represent the mean kinematic ratio measured for all systems and for the azimuthally selected subsample of systems, respectively.
