〈X_i,ICF〉 for neon, argon, sulfur, nickel, and iron in the varied (n_e, T_e) prescription. Abundances are given in dex relative to solar. This figure uses the lower limit on the ICF corrections, while the full range of 〈X_i〉 with and without ICF corrections is provided in Table 2. Uncertainties are given as the standard deviation across Regions 1–3. GC literature values are included for the central 1.2 pc ionized gas (J. C. Shields & G. J. Ferland 1994; blue Bar), the minicavity (D. Lutz et al. 1993, with and without their inferred ICF; empty and filled black squares, respectively), the Bubble (J. P. Simpson et al. 2007; gray diamond), the IRS 13 X-ray plasma (Z. Hua et al. 2023; gray stars), and the central parsec X-ray plasma (M. Balakrishnan et al. 2026a; gray cross). We find mildly supersolar argon and neon, sub- to supersolar sulfur and nickel, and mildly supersolar gas-phase iron.
