Fig. 7
Spatial distribution of the formal position uncertainty in Eq. (1) for the 407 959 sources of the Gaia-CRF2 with G < 20. The map shows the median value in each cell of approximately 0.84deg2, using a Hammer–Aitoff projection in Galactic coordinates with zero longitude at the centre and increasing longitude from right to left. The solid black line shows the ecliptic.
