Notes. The numbers inside parentheses indicate the sensitivity of the orbital elements to the different angular velocity of the bar (Ωbar), which we have computed as the standard deviation of the orbital elements when considering three different values for the bar pattern speeds, Ωbar = 33, 43, and 53 km s−1 kpc−1. (†) Moreno et al. (2014); († †) Baumgardt et al. (2019; *) Pérez-Villegas et al. (2020); input parameters employed in this study were taken from Vasiliev (2019). Moreno et al. (2014) and Baumgardt et al. (2019) used Ωbar = 55 km s−1 kpc−1 and Pérez-Villegas et al. (2020) used Ωbar = 45 km s−1 kpc−1.
