Notes. (1) As listed in Perryman et al. (1997); (2) F. van Leeuwen (2007); (3) Sousa et al. (2008); (4) this work: mean and standard deviation; (5) Estimated from using the relationship by Mamajek & Hillenbrand (2008). The reported uncertainty is the quadratic addition of the individual errors propagated from the uncertainty and the deviation in the values produced by the change in the activity level; (6) Measured in the FWHM, and/or bisector time series.
