Counts in the sky for a selection of stars that favours the outer disc structures. The selection is for stars with ϖ < 0.1 mas, − 1 < μ_α* < 1 mas yr⁻¹ and − 2 < μ_δ < 0 mas yr⁻¹. Left: DR2 (we observe marks of the scanning law). Right: EDR3 (with more stars and better homogeneity) without filters nor parallax zero-point correction. The ACS can be seen more clearly in the right panel.
