Notes.

(a)

Unchanged from Sander et al. (2012).

(b)

All distance moduli based on Gaia DR2 parallaxes converted into distances by Bailer-Jones et al. (2018).

(c)

Masses are calculated from luminosity after Langer (1989) using their M−L relation for WC stars.

(d)

Binary candidate with possibly significant contribution from the secondary. See comments in Sect. 3.5.

(e)

Binary system analyzed as a single source. See comments in Sect. 3.5.
