AMR of our sample of dynamically selected GSE GCs. Candidate in-situ clusters (namely NGC 288 and NGC 6205) are shown as open circles. GCs with uncertain membership to GSE (namely NGC 5286 and NGC 7099) are shown as filled black triangles. The metal-rich, in-situ GCs analysed in Paper I are shown in grey for the sake of comparison, with the younger and older groups marked with different symbols. A representative AMR model for the GSE genuine members is also shown as a solid black line.
