Full-sky maps of the mean parallax differences (units: μas; color bars) for the five-parameter solutions of ΔπEDR3 and ﹩{\rm{\Delta }}{\pi }_{\mathrm{EDR}3}^{\mathrm{corr}}﹩. The top two panels show Hammer–Aitoff projections of ΔπEDR3 and ﹩{\rm{\Delta }}{\pi }_{\mathrm{EDR}3}^{\mathrm{corr}}﹩ in ecliptic coordinates; the bottom two panels are in Galactic coordinates. The resolution of each pixel before smoothing is 3 × 3 deg2. We only kept pixels with mean parallax differences estimated from more than 10 EWs. The solid black lines in all panels denote the Galactic plane. The Galactic center and anticenter are shown as black and gray bullets, respectively.
