Abstract
Multi-band surveys such as the Southern photometric Local Universe survey (Mendes de Oliveira et al. 2019) have a key advantage: the narrow band that covers the magnesium triplet (filter J0515) is sensitive to the surface gravity of stars, which allows the selection of distant giant stars (e.g. Majewski et al., 2000). Cleaning the sample of nearby dwarf stars is crucial, as they can corre…
