Difference between our E-G and the Gaia DR3 PMs as a function of (from top to bottom) x position, y position, G magnitude, and (BP – RP) colour. The left column refers to the µ_α cos δ component of the PM, whereas the right column focuses on the µ_δ component. In all plots, the red dashed line is set to 0 as a reference. Blue points are the median values (and their errors) of the Δ PM in bins of size 2500 pixels (first two rows from the top; step of 1250 pixels) or 0.25 magnitude (the other panels; step of 0.125 magnitude).
