a–d, All elements (a), heavy elements (b), iron-peak elements (c) and siderophile elements (d) for all 14 reservoirs. The CI reservoir is clearly separated from the other reservoirs of the CC group. The NC group can also be divided into two subgroups; the ureilities and the Vesta group represent a population distinct from those of the group consisting of H, L, LL (OCs), Mars, EH and EL (ECs), collectively the OC–EC subgroup. The BSE is an extension of the OC–EC subgroup for all element groups, regardless of their chemical or nucleosynthetic affinity. Open circles are computed from deterministic PCA. Transparent circles show the 104 samples from the posterior distribution and filled squares are the means of the B-LFA posterior. The arrows denote the loading vector for each isotopic ratio to the LFs (for example, a reservoir with high ε100Ru will plot to lower values of LF1 at near-constant LF2 in d).
