Comparison of the Keplerian solutions for the trajectory of X7 between Ciurlo et al. (2023) and this work. We implemented the measured data points that are listed in the Appendix. In the upcoming epochs, we will be able to test the validity of the presented orbital solutions. However, L-band data from 1999 already reveals a strong tendency that favors the presented orbit in Table 5. This data point is represented by a black plus sign (+) in the figure above (see the text for details).
