Same diagnostic diagrams as shown in Fig. 7 (dotted black and red lines are the starburst limit and photoionization models described therein), now including the velocity (v) and magnetic field (B) grid (dashed and solid lines) for the best-fitting shock models from Allen et al. (2008), in which the preshock density n = 1 cm−3 and the chemical abundances described in Dopita et al. (2005) were used.
