Notes. 1 = Torres et al. (2008a), 2 = Reynolds et al. (2006) 3 = this paper. R-band magnitudes and X-ray luminosities are taken within one day of the optical spectra (Torres et al. 2008a, this paper). X-ray luminosities are from RXTE/PCA are based on a distance of 2.8 kpc as adopted in Sect. 10.3 of Torres et al. (2008a).
