Notes. The horizontal line separates stars analyzed within this work (drawn from Mas04/05/09) from stars previously analyzed in Paper II. Identifications are as follows: “AV” from Azzopardi & Vigneau (1982); “BAT” from Breysacher et al. (1999); “BI” from Brunet et al. (1975); “LH” from Lucke (1972) except “LH10-3058” that is from Walborn et al. (2002, 2004); “N11” from Evans et al. (2006); “NGC” from Massey et al. (1989); “P” from Parker et al. (1992); “R136” from Massey & Hunter (1998); “R136a” from Malumuth & Heap (1994); “Sk” from Sanduleak (1970).
