Notes. Nomenclature according to Claria & Lapasset (1991). The symbol : is used to indicate extrapolated values. g is the stellar surface gravity given in cm s^-2.

^(dd)

Stars with double Balmer discontinuity.

^(mk)

Spectral types derived using the MK-system.

^(Be)

Known Be star.

^(pv)

Identified as a photometric variable by Lapasset et al. (1991).

^(a)

Values interpolated from Cox (2000).

^(m)

Values determined using the relation between Φ_b and (B − V) given by Moujtahid et al. (1998).
