Notes. “Group” indicates whether the star has been selected within the tidal radius of H4 (A), or whether it is a field star from the central part of Fornax (B). For stars of category A, the seperation index msep is an indicator for the flux contamination of a spectrum, as described in Sect. 2.2.1 of the main article. The S/N is per pixel of the degraded spectra as they are supplied to SP_Ace. The effective wavelength range Δλeff gives the final wavelength range which is used in the chemical analysis after critical regions flagged in various pixel masks have been removed.
