Distribution of distant halo stars, selected by excluding the Galactic plane and a cut in median distance (|b|> 15 deg, dist50 > 10 kpc; 2.55M stars). Top panel: sky distribution in ecliptic coordinates, highlighting the presence of the Sagittarius stream close to the ecliptic plane. Middle panel: same projection, colour-coded by the median distance per HealPix. In both panels the contour overlay shows the location of the Sagittarius stream candidates from Antoja et al. (2020). The bottom panel shows a Cartesian projection (X_Gal vs. Z_Gal), highlighting some of the less prominent Local Group objects included in the priors.
