Notes. We also provide known spectral types when available, from Bresolin et al. (2007), Garcia et al. (2010, in prep. †) or Lozinskaya et al. (2002, ‡). For reference, photometric properties (observed V-mag., Q color and reddening correction ΔV), log age, their host association and the Paper I figure where they can be found are listed.
