Notes. We only found poor fits for the sources listed at the bottom. (†)New spectral type determined using XShootU data (Bestenlehner et al., in prep.). Spectral type reference: a: Walborn et al. (2000), b: Lamb et al. (2016), c: Evans et al. (2004b), d: Lennon (1997), e: Garmany et al. (1987), f: Walborn et al. (2002). (⋆)The absolute Ks magnitude was also corrected for line-of-sight extinction.
