Notes. Flux (zeroth moment) and velocity dispersion (second moment; σ) measured at the AGN, N2, and S2 regions. The diameter of the apertures is 1″. A point-source aperture correction is applied to the AGN spectra. The quoted uncertainties are 1σ statistical uncertainties. The absolute calibration uncertainty is ∼10% (Rigby et al. 2022). For the non-detections, we list the 3σ upper limits for a line with a width of ∼200 km s−1.

a

Ionization potential of the transition defined as the energy needed to reach the ionization stage producing that transition (Kramida et al. 2022).

b

Critical density at T = 10000 K for collisions with e calculated using PyNeb v1.1.15 (Luridiana et al. 2015).
