Position on the sky (left) and location on the RGB (right) for our Sculptor stellar sample, based on Gaia DR3 (Table 2). Star symbols with labels are stars with new spectra, which are analysed for the first time here; whereas, large blue circles are stars with available literature spectra, which are re-analysed here. Small, light blue points are stars from Gaia eDR3 within a 1.5 deg radius of the centre of Sculptor.
