Same planes as in fig. 5. Programme targets are marked by filled stars: grey for unclustered, green blue and light blue for the three identified clusters. Blue and green clusters can be associated to stars classified as GSE and bulge in section 4. Yellow points are stars from Bonifacio et al. (2021). The areas used to select GSE and Seq stars in section 4 are still outlined here for reference but using red and green squares in the bottom middle and right panels, respectively.
