Ensemble of ten thousand orbits for the two HVNS candidates 2M17025992−3537464 and 2M19175783−1343049, projected on the equatorial (top) and meridional (bottom) Galactic planes in the inertial reference frame with a bar pattern speed of 41 ± 10 km s−1 kpc−1, and time-integrated forward and backward over 1 Gyr. The yellow and orange colors correspond to more probable regions of the space, which are most frequently crossed by the simulated orbits. The black dashed and solid black lines show the 50th percentile for the forward and backward orbital path, respectively. The top panels show, for guidance, a MW bulge (solid white circle) and disk (white dashed circle) radius of ∼3.5 kpc (Barbuy et al. 2018) and ∼15 kpc, respectively. While the MW disk extension until ∼15 kpc is also denoted by a thick white line in the bottom panels. Columns (1) and (3) show the orbital configurations by assuming the Bayesian StarHorse distances, whilst Cols. (2) and (4) display the predicted orbits by adopting the Bailer-Jones geometric distances.
