Chemical abundance patterns. From left to right, we show the position of M4327 in the N/O vs. O/H, Ne/O vs. O/H, and O/Ar vs. Ar/H diagrams. A compilation of local galaxies and HII regions with T_e-based abundance measurements from CHAOS (Berg et al. 2016), BOND (Vale Asari et al. 2016), and DESIRED (Méndez-Delgado et al. 2024) is shown for comparison, together with the sample of Wolf-Rayet galaxies from López-Sánchez & Esteban (2010). In the O/Ar vs. Ar/H diagram, we overplot the galactic chemical evolution tracks for the MW (solar neighborhood, orange) and the disc of M31 (between 3 and 14 kpc, purple) from Kobayashi et al. (2020) (see also, Arnaboldi et al. 2022).
