Notes.

^(a)

Subscript “1” and “2” denote primary and secondary, respectively. The secondary component is not detectable from multicolour photometry.

^(b)

Z_⊙ = 0.02 dex.

^(c)

The adopted values are compromises between photometric and spectroscopic determinations where both are available.

^(d)

The log g is photometrically not constrained.
