Notes. Quoted uncertainties on ⟨[Z/H]⟩ and ⟨log₁₀ Age/yr⟩ are formal errors propagated as described in the text; σ_int gives the intrinsic dispersion of the corresponding PDF where applicable. Errors on masses and SFRs that depend on distance are dominated by the adopted distance D = 17 ± 1.5 (stat.) ± 1.0 (syst.) Mpc. ^(a)MeerKAT H I mass from Serra et al. (2024). ^(b)3σ upper limit on the molecular H₂ mass from ALMA CO(1–0) observations (Zabel et al. 2019, Appendix C.4), rescaled to our adopted distance. ^(c)Warm H₂ mass lower limit from the Spitzer/IRS analysis of Sivanandam et al. (2014), assuming OPR of 1.5. ^(d)Dust masses from the two-component modified-blackbody fit to the IRS LL + Herschel SED (Appendix C.3), measured within an aperture comparable to the μ₀+1 isophote. The total dust mass may be larger by up to a factor of ~2 if the cold component follows the more extended 20–38 μm emission out to μ₀+1. ^(e)Values rescaled to the adopted distance of 17 ± 2.5 Mpc; quoted uncertainties include distance contributions.
