(a) Initial distribution of the fragments from SATCOM 3 and ATLAS 5 CENTAUR R/B in mean elements (a, e, i). (b) Evolution of mean elements (orange) and proper elements (blue) for both groups of fragments in the \(e-i\) plane. (c) The evolution of the estimated PDF in inclination over 20 years in mean (orange) and proper (blue) elements. (d) Accuracy over time of DBSCAN for mean (orange) and proper (blue) elements (using the same set of parameters).
