Comparison with stars in Anguiano et al. (2025) (A25). Top row, left panel: number of stars in the A25 sample that, according to our analysis, have a null (P = 0), not null (0 < P < 0.7) or high (P ≥ 0.7) probability of being chemically compatible with ω Cen. Top row, middle panel: distribution of probabilities P (magenta) of the stars of A25’s sample which, according to our analysis, have a not null probability of being chemically compatible with ω Cen, compared to the analogue distribution of probabilities P_A25 (cyan) provided by A25. It can be noted that part of the stars which have a high P_A25 turns out to have a low P, according to our GMMChem model. Top row, right panel: distribution in the E-L_z plane of Nephele candidate members (P ≥ 0.7, magenta), compared to that of stars in A25 (cyan) which have also a high P, according to our analysis, of belonging to Nephele. Middle row, left panel: normalised [Fe/H] distribution of A25's stars which are classified as Nephele candidate members (P ≥ 0.7) also by our GMMChem model (cyan). For comparison, the normalised [Fe/H] distribution of ω Cen stars is also shown. Middle row, middle panel: same for A25's stars which have a moderate probability (0 < P < 0.7) of being chemically compatible with ω Cen, according to our GMMChem model. For comparison, the normalised [Fe/H] distribution of ω Cen stars is also shown. Middle row, right panel: same for A25's stars which have a null probability P of being chemically compatible with ω Cen, according to our GMMChem model. For comparison, the normalised [Fe/H] distribution of ω Cen stars is also shown. Bottom row, left panel: distribution in the [Mg/Fe] vs [Fe/H] plane of stars in the A25's sample. Blue points indicate A25's stars which have not been analysed in our work, cyan points indicate A25's stars for which a probability P has been assigned by our GMMChem model. Cyan crosses indicate A25's stars which have a P = 0, according to our GMMChem model. The corresponding distribution of ω Cen stars in this plane is also shown (light grey points). Bottom row, middle panel: same for [Al/Fe] vs [Fe/H]. Bottom row, right panel: same for [Al/Fe] vs [Mg/Fe].
