Notes. The B and V magnitudes were sourced from the GCPD catalogue (Mermilliod et al. 1997) with N number of references. In cases where the B and V were not found in the GCPD catalogue, they were taken from the Simbad database. The J2MASS and K2MASS magnitudes are sourced from 2MASS (Cutri et al. 2003). All parallaxes were taken from a reanalysis of the Hipparcos catalogue (van Leeuwen 2007). The adopted reddening values were taken from Meléndez et al. (2010), Casagrande et al. (2010, 2011).
