[Fe ii]/[O iv] vs. [O iv]/[Ne ii] diagram for GOALS sources. The symbols are the same as Figure 7, but here we also indicate the sources which lie on the shock model grids in Figure 7 as the blue stars. The two large diamonds at the top right are supernovae IC 443 and RCW 103 (Oliva et al. 1999a, 1999b) for comparison. The grids are simple mixing lines from Lutz et al. (2003) which indicate contribution of shocks from supernova remnants or AGNs (0%, 10%, 20%,...).
