Sagittarius stream in our RGB catalogues. Photometric distance versus RA in the PDR1-giants catalogue at higher metallicities ([Fe/H]>-1.0, top), close to the Sagittarius stream plane (IBI<20°, middle), and the latter for the PGS-giants catalogue (bottom). All panels have Sagittarius stream tracks adapted from Hernitschek et al. (2017). Note the spur feature (associated with feature 3 from Sesar et al. (2017). Leading and trailing arms are respectively labelled ‘L’ and ‘T’. The stream members go further out and are more prominent with PDR1-giants than PGS-giants mostly due to the distance-metallicity selection effect in the latter catalogue.
