M_sp [M_⊙]	22.2 ± 0.5^d

Notes.

Adopted. Errors represent values consistent with T_eff determination, but a lower log g already corresponds to the luminosity class III.

Adopted from Riquelme et al. (2012). Uncertainties depend on the deviation from the standard extinction law, which cannot be quantified.

Formal error due to uncertainty in distance. The dependence on A_V cannot be quantified.

Formal errors from the procedure. Dependence on distance ignored.
