Notes. Columns indicate statistical results for the distribution of the observed ratios (obs), and of the extinction corrected values (corr). Last column (N_spaxels gives the number of spaxels for each galaxy.

^(a)

Statistics using only the spaxels were [SiVI]1.96 μm emission line has been detected.

^(b)

Statistics using all the spaxels within the field-of-view with no [SiVI]1.96 μm emission line detected.
