Notes. (†) Rotation velocity (km s-1) at 100 AU, which determines the stellar mass M ∗ . (a) at 100 AU, (b) at 300 AU. (1) A number between brackets [] indicate a fixed parameter. (2) Large errorbar due to strong coupling with temperature. (3) Error bar not symmetric; derivation from covariance matrix inaccurate.
