Previous studies have collected a few thousand spectra of the inner NSC, and also the outer NSD, and measured line-of-sight velocities and metallicities. Until now, such measurements exist only for a few 100 stars in the region where the stellar surface density transitions from being dominated by the NSC into being dominated by the NSD.
