Notes. ^a The first reference is the membership (region) reference whilst the second is the SpT reference. If there is only one reference it means that both the region and SpT information were retrieved from that work.

^b Literature SpT based on optical data.

^c Known unresolved binary, the SpT given is the unresolved classification. ^d Uncertain membership. Object discussed in Appendix C.

^e Combined spectral type, derived from a mixture of their own classification (optical or NIR) and literature.

^f Final SpT classification adopted throughout the analysis (see Sect. 4.1).
