Notes.The primary star identifications are “MPG numbers” from Massey et al. (1989) or “NGC346-XXX numbers” from Evans et al. (2006) for stars in NGC 346. We use AzV numbers (Azzopardi et al. 1975; Azzopardi & Vigneau 1982) for SMC field stars. The color excess, E(B − V), is divided into two contributions from the Galactic foreground and the SMC field and is derived from this study (see Sect. 3.2). The following sources were used for coordinates, spectral classification, and photometry: 1) Massey et al. (2009); 2) Massey et al. (2005); 3) Massey (2002); 4) Evans et al. (2006); 5) Mokiem et al. (2006); 6) Massey et al. (1989).
