Notes. Upper limits are indicated by < in the fifth column and the number of lines used for the measurement nl is given in the sixth column. Abundances have been estimated with fixed ξm = 10 kms-1 (see Sect. 3.4). Key parameters that are used in this paper (νesini, Y, log  gc, Teff, log  L, Mevol) were determined by Ramírez-Agudelo et al. (2017). Newly detected binaries are shown in a separate segment; see Sect. 3.4 for a discussion.

(a)

Spectral types as given by Walborn et al. (2014);

(b)

The errors are computed from the standard deviation between measurements from individual lines. They do not incorporate the uncertainties in the atmospheric parameters and continuum normalisation (see Sect. 3).

(c)

Y is the surface helium mass fraction;

(d)

log  gc (cgs) is the logarithmic surface gravity corrected for centrifugal force;

(e)

evolutionary masses Mevol are determined with Bonnsai (Sect. 6.1). An electronic form of the table is available at the CDS.
