Notes. (*)Star IDs are from Carretta et al. (2011), V and B magnitudes from Stetson et al. (2019). The stars were divided into the metal-poor and metal-rich sub-samples according to criteria described in Sect. 3.1. (* *)The median S/N values per pixel in the blue wavelengths at λ 4800−5750 Å, and in the red wavelengths at λ 5850−6800 Å, accordingly.
