Galaxy-by-galaxy comparison of j_t determinations of this work and Romanowsky & Fall (2012) for the subset of ePN.S galaxies in common. Galaxies without error-bars on the y-axis are those for which Romanowsky & Fall (2012) used the approximation j_t ∝ R_eV_rot(2R_e), see their Eq. 6. The discrepancies between measures can be partially explained by the assumption of cylindrical velocity fields in Romanowsky & Fall (2012), which lead to an overestimate of j_t. Symbols as in Fig. 12.
