In their calculation of transport due to ripple trapping, Connor and Hastie employ a factor G(α) to take into account the poloidal variation of the depth and shape of the local magnetic wells. They assume, however, that the toroidal-field ripple strength, δ, is independent of the poloidal angle. This letter generalizes G to treat any arbitrary poloidal variation of δ, and also high-beta, non-circular plasma configurations of arbitrary aspect ratio.
