Notes. (a) HD 20782, the stellar visual companion of HD 20781, hosts a planet as well. The corresponding stellar parameters are given in Jones et al. (2006). (b) Astrometric and visual photometric data from the HIPPARCOS Catalogs (ESA 1997; van Leeuwen 2007). (c) From Sousa et al. (2008) spectroscopic analysis. (d)Parameter derived using HARPS spectra or CCF. (e)From the calibration of Mamajek & Hillenbrand (2008).
