Best-fit single orbit of Jhelum in the default MW potential for σnuis = 6.7 km s−1 (dark blue line) and σnuis = 2 km s−1 (dashed light orange line). 100 orbits were sampled randomly from the MCMC chains for the higher and lower values of σnuis, and are shown in light indigo and in orange respectively. The binned estimates and their 1σ uncertainties are plotted in red, while the individual RV-NC-stars (along with their names) are plotted in blue for σnuis = 6.7 km s−1 (and light-blue for its smaller value). Though the orbits follow the binned track and RV-NC-stars well within the error bars in position and PM, in radial velocity no orbits go through all of the four RV-NC stars: Jhelum2_14 and especially Jhelum1_5 lie far outside the sampled range in radial velocity. The distance to the stream is somewhat low in comparison to the estimate by Shipp et al. (2018), but consistent with the estimate by Li et al. (2022).
