Fig. 9.


Comparison between the TGAS parallaxes and the maximum a posteriori estimates from the HM. The error bars correspond to the TGAS parallax uncertainties (horizontal) and credible intervals calculated as the median plus minus the difference between the median and the 84th and 16th percentile (vertical). The red circles correspond to stars with parallax difference beyond twice the combined uncertainties.
