Values in column three are 
uncorrected for reddening. In column four the dereddening parameters used to correct our optical photometry computed 
assuming $E(B-V)=0.79 \pm 0.05$~mag are reported. The absolute magnitudes are computed assuming a distance of 8~kpc 
(Campana et~al. 2005; see Sect.~4.2.1 for details).
