Top left panel: the Galactic Mollweide projection of LSDR9 stellar objects selected using Equation (2). The highlighted regions represent the location of known substructures: Sagittarius stream (pink), HAC-S (yellow), HAC-N (red), Pisces (green), VOD (blue), and OVO (cyan). Top right panel: the Galactocentric BHB stellar density profile of the whole LSDR9 footprint and without HAC-S, HAC-N, and VOD regions as the solid and dotted markers, respectively. Bottom panels: the Galactocentric radial density profiles for the Galactic regions associated with HAC-N, HAC-S, VOD, and Pisces. The crosses correspond to twenty and ten radial bins equally spaced in logarithm within 5 < r_q/kpc < 120 for LSDR9 footprint and overdensities, respectively. We also show the resulting fit for 100 samples drawn from the posterior distribution as the solid lines.
