Comparison with the calibration of Stanghellini et al. (2017). The red symbols show targets with TGAS parallaxes, the blue symbols represent the USNO targets, and black symbols show our larger sample based on SH10. Red fit lines use the same targets as in the previous study, but using GDR2 distances. The black fit line uses the complete sample based on SH10. SaSt 2-12 is marked with an open symbol. The dash-dotted magenta lines show the fits by Stanghellini et al. (2017).
