Diagnostic diagrams. Top, left to right: Standard optical log([O III]/Hβ) versus log([N II]/Hα) and log([O III]/Hβ) versus log([S II]/Hα) diagnostic diagrams. Different ionization regimes are separated by solid and dashed black lines, taken from Kewley et al. (2001, 2006) and Kauffmann et al. (2003). Dashed-dotted black lines show the observed position of z≃2−3 star-forming galaxies in Strom et al. (2017). Bottom, left to right: Diagnostic diagrams log([O III]λ4363Å/Hγ) versus log([O III]λ5007Å/[O III]λ4363Å), log([O III]λ4363Å/Hγ) versus log([O III]λ5007Å/[O II]λ3727Å), and log([O III]λ4363Å/Hγ) versus log([Ne III]λ3869Å/[O II]λ3727Å) and demarcation lines from Mazzolari et al. (2024). Total, narrow, and outflow component line fluxes are shown as circles, squares, and pentagons. COS2949 is marked as a pink line since NIRSpec/IFU data do not cover the Hβ+[O III] range. Error bars are dominated by the uncertainties resulting from extinction correction.
