Orbital parameters are compared with Pourbaix (2000); Jancart et al. (2005); Gallenne et al. (2019); Kiefer et al. (2018, 2016); Halbwachs et al. (2020); Eker et al. (2014); SB9 (Pourbaix et al. 2004); APOGEE DR16 apjoker orbits (Price-Whelan et al. 2017); APOGEE SB2 (Kounkel et al. 2021); Orb6 (http://www.astro.gsu.edu/wds/orb6.html).

The proper motions of the NSS solutions are compared with the long term proper motion obtained from the Hipparcos-Gaia positions (Kervella et al. 2022).
