Metallicity differences between inner and outer galaxy regions inferred from the near-IR spectra.
|Name||12 + log(O/H)inner||12 + log(O/H)outer||Δ 12 + log(O/H)|
Notes. Column 1, object name; Col. 2, gas metallicity of the inner aperture within a radius of 0.375′′; Col. 3, gas metallicity of the outer region within a radius of 0.375′′ < r < 1′′; Col. 4, metallicity difference between inner and outer regions.
