Density-sensitive ratio of [NeV]14.3/24.3 as a function of electron density modeled with PyNeb (version 1.1.19; Luridiana et al. 2015). Solid and dashed lines correspond to electron temperatures of 104 and 2×104 K, respectively. The values of the flux ratio measured from the nuclear spectra are shown as dotted lines of different colors, and the upper limit measured for J1010 as dot-dashed line.
