Same as Figure 11 but for [O II] 3726, 9/[O III] 5007 vs. [Ne V] 3426/[Ne III] 3869 line ratios and different grid values for the shock velocity. The shock and precursor model grids show five shock velocities of 200, 400, 600, 800, and 1000 km s⁻¹, as model grids for shock velocities below 200 km s⁻¹ extend far beyond the axis limits. The shock+precursor model successfully reproduces most of the observed line ratios, while the AGN photoionization model fails to account for most of the spaxels in the galaxy.
