Left: Δ_ϖ (top) and the scaled Δ_ϖ (bottom) versus magnitude for the whole sample after the correction to the parallax zero point is applied. The solid lines show the LOWESS of the stars bluer (redder) than G_BP − G_RP = 0.9 mag (blue and red lines). The black line is the for the whole sample. Right: CMD of the whole sample where the colour shows the differential parallax to the median, and the analogous scaled to the nominal parallax uncertainties after parallax zero point correction (see text for details).
