Table A.1.
O+ and O2+ chemical abundance measurements for all the catalogues analysed in this work. The asterisk refers to indirect Te estimates using Te-Te relations. In particular, in PHANGS-MUSE analysis Te[O III] is estimated from Eq. 1, while in Nakajima’s analysis Te[N II] is estimated from Te[O III] using the Te-Te relation from Rogers et al. (2021).
