Notes. (1) Spectroscopic (d) and trigonometric (dϖ) distances are assummed to follow the relation d = kdϖ. (2) Hipparcos stars with a trigonometric distance error smaller than 20%, a spectroscopic distance error below 32% and with RAVE spectra with S / N > 40. (3) A subset of Sample A where all four calculations find a spectroscopic distance error smaller than 32%.
