Notes. Column descriptions: Teff [K]: adopted effective temperatures, based on the Casagrande et al. (2008) calibration and FeH spectrum adjustment. † and †† denotes an increase in the photometric temperature by +100 and +200 K, respectively. Teff [K] (WL11): effective temperatures derived from the Worthey & Lee (2011) calibration. Parallaxes are from Hipparcos (van Leeuwen 2007) for all targets except for GJ 317 (Johnson et al. 2007) and GJ105 B (Jenkins et al. 2009).
