We have noticed an error in the radial metallicity gradient fits provided in Table 3 (Appendix C) of the published article. The columns that list the metallicity gradients have units of dex arcmin⁻<fnref n="1" />, rather than the noted dex kpc⁻<fnref n="1" />. In the following we provide a corrected version of the table. All figures in the published article are shown in units of R25, and are unchanged from the published version. The results and conclusions of the paper are not affected by this error.
