Sky distribution (equatorial coordinates) of the 2 005 683 observations for the 14 124 asteroid in the validation sample. This sky map use an Aitoff projection in equatorial (ICRS) coordinates with α = δ = 0 at the centre, north up, and α increasing from right to left. The observation density is higher in blue areas. The pattern in ecliptic longitude is a consequenceof the Gaia scanning law over a small fraction of the five-year nominal mission.
