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.
