Comparison of trigonometric parallaxes determined in this work with the published parallaxes given in Hipparcos (van Leeuwen 2007) and Weinberger et al. (2013). The dotted line represents perfect correlation. TWA 23, which was measured by us and by Weinberger et al., sits almost under TWA 1. The error bar on our measurement is +/−1.8 mas.
