^a Column (8) Applied reddening law: S = Seaton (1979), C = Cardelli et al. (1989), F = Fitzpatrick (1999); for the last two, the given number is the adopted R_V.
^b Binary system in which the non-WR component contributes more than 15% of the flux in the visual.
$^\dagger$ Mass-loss rates are for an adopted clumping factor of D = 4.
