| AgeLW (Gyr) | [M/H]LW (dex) | [Mg/Fe]LW (dex) | AgeMW (Gyr) | [M/H]MW (dex) | [Mg/Fe]MW (dex) | |
|---|---|---|---|---|---|---|
| NSC | 11.1 ± 0.5 | −0.55 ± 0.02 | 0.07 ± 0.03 | 11.5 ± 0.5 | −0.49 ± 0.03 | 0.03 ± 0.02 |
| Host | 4.7 ± 0.4 | 0.24 ± 0.02 | 0.03 ± 0.01 | 9.1 ± 0.7 | 0.25 ± 0.03 | 0.15 ± 0.02 |
| Original | 6.8 ± 0.7 | −0.23 ± 0.03 | 0.07 ± 0.02 | 9.6 ± 0.8 | −0.27 ± 0.03 | 0.02 ± 0.03 |
Notes. These values were obtained, as detailed in Sect. 4.2, from spectra integrated in a 1σ PSF aperture. From top to bottom, the rows present the NSC, the host galaxy (decomposed as explained in Sect. 4.1), and all components combined in the LOS (obtained from the original – kinematic-corrected – data cube). From left to right, columns indicate the light-weighted (LW) average age, the total metallicity [M/H] and [Mg/Fe] abundances, the mass-weighted (MW) average age, and [M/H] and [Mg/Fe]. Uncertainties were obtained via Monte Carlo simulations (Sect. 4.2).
