Smoothed maps of quasar parallaxes and proper motions. Left column: Gaia EDR3, using data for about 1.2 million quasars. Right column: Gaia DR2, using data for the 94% of the quasars in the left column that have full astrometric solutions also in DR2. From top to bottom the maps show parallax, proper motion in right ascension, and proper motion in declination. The maps were smoothed using a Gaussian kernel with standard deviation 5°. No data are shown for | b | < 10°, where b is Galactic latitude.
