Notes.
Name as in Alves de Oliveira et al. (2010), where additional information regarding each target is included.
Based on the tests performed to the spectral fitting method, uncertainties on the spectral type and AV are estimated as 1 spectral subclass and 1 mag, respectively.
See Sect. 6.2 where the temperature scale applied is explained.
See Sect. 4.1.2 for the discussion.
