Notes. We adopt a distance of ~ 5 kpc (Negueruela et al. 2010) and with AV ~ 10.66 (Sect. 3) determine that MV = −6.63 (implying a bolometric correction of −2.1 mag). We note that R∗ corresponds to R(τRoss = 2/3). The H/He ratio is given by number and other abundances are relative to solar values from Anders & Grevesse (1989); if we use the values from Asplund et al. (2006) as a reference, the derived ratios need to be scaled by 1.38, 1.537 and 1.86 for C, N and O respectively. Finally, our derived H/He abundance corresponds to a surface helium mass fraction, Ys = 0.49.
