Comparison of HWHM velocities vs. absolute magnitudes of Magellanic Cloud PNe with different model predictions as indicated in the legends. The dashed-triple-dotted line correspond to the V_agb = 7.5 km s^-1 sequence. The velocity measurements are again from Dopita et al. (1985, 1988), but here V_HWHM is shown, instead of their V_exp, against M(5007) (left) and M(Hβ) (right). The 5007 Å fluxes are from Jacoby et al. (1990). True distance moduli and extinction values c used are 18.37 and 0.28 for the LMC and 18.72 and 0.26 for the SMC (Dopita et al. 1992).
