Table 4:

Measured emission-line ratios in 3C 326 N and expected ratios for a pure-shock model and a model assuming a shock and precursor (Allen et al. 2008).
Line ratio	Observed	Shock	Shock and precursor
H $\beta$ /H $\alpha$	0.26	0.33	0.33
[OIII ]/H $\beta$	0.72	0.82	1.48
[OI ]/H $\alpha$	0.24	0.22	0.13
[NII $~]\lambda$ 6584/H $\alpha$	0.77	0.68	0.47
[SII ]/H $\alpha$	0.61	0.52	0.32
[SII $~]\lambda$ $\lambda$ 6716,6731	1.32	1.23	1.24
[NeII ](12.81 $\mu$ m)/H $\alpha$	0.46	0.45	0.28
[NeII ](12.81 $\mu$ m)/[NeIII](15.6 $\mu$ m)^a	>1.8	2.2	0.73
