Appendix A: Other measurements

Skillman et al. (2003) have obtained emission-line spectroscopy of late-type dwarf galaxies in the Sculptor group with the 4-m telescope at CTIO. Their sample included ESO347-G017, ESO348-G009, and UGCA 442; they measured [O III] $\lambda 4363$ in ESO347-G017 and UGCA 442. Our bright-line oxygen abundances for ESO347-G017, ESO348-G009, and UGCA 442 agree with the abundances obtained by Skillman et al.
