Note: in the following plots black denotes returning clones while red denotes escaping ones.The nominal solution is located at the center of the green circle. Each plot have a header where date of calculation and some other parameters are coded. Also numbers of returning (B=shown+omitted), escaping (C=shown+omitted) and all (T=shown+omitted) Vcs are shown.
Past orbit, at previous perihelion for the returning VCs :
Past, gravitational.
Past, gravitational, asynchronous,
escape border extended up to 170 000 AU.
Past, gravitational, synchronous,
escape border extended up to 170 000 AU.
Past, nongravitational, asynchronous.
