Age gradients in LTGs steepen with increasing galaxy mass, from $-0. 05\pm0. 11~\log$ Gyr/R$_e$ for the lowest mass galaxies to $-0. 82\pm0. 08~\log$ Gyr/R$_e$ for the highest mass ones.

We reveal a mutual correlation between steep oxygen abundance profiles between $0. 25-1. 5 R_e$, increased variability of metallicity between $1. 25-1. 75 R_e$, and elevated HI content at fixed total galaxy stellar mass.

We summarize assessments of the precision and accuracy of our measurements as a function of signal-to-noise and other salient metrics, noting that additional analysis and discussion of emission-line diagnostics are provided in our companion paper, Belfiore et al.
