Line ratios to Hβ λ4861 versus shock velocity according to the MAPPINGS III code for LMC abundances, magnetic field strength of 10-4μG and an ambient density of 1 cm-3 for the shock component only. Points are numeric data and lines represent interpolated curves. Values are normalized to their results for vs = 150 km s-1. Colors identifying each line ratio are the same as in Fig. 13.
