Fig. B.1


Parallax difference between TGAS and Hipparcos plotted against the weighted mean parallax (Eq. (B.5)) for three different weight factors x: a) x = 0, i.e. the abscissa is the TGAS parallax; b) x = 0.1; and c) x = 1, i.e. the abscissa is the Hipparcos parallax. See text for further explanation.
