Rotation-to-velocity dispersion ratio as a function of GC ellipticity. The sample of GCs with known Arot/σ0 values comes from Bellazzini et al. (2012); Bianchini et al. (2013) and the ellipticity information is taken from Harris (1996, 2010 version), except for NGC 4372 (red star), for which we use our own estimates. A model of an isotropic, rotating spheroid is superimposed for comparison (Binney 2005).
