After the filtering and rejection procedure, the second
Gaia data release contains 14 099 solar system objects,
corresponding to 1 977 702 observations and 287 904
transits. The distribution of the residuals in the AL and AC directions are clearly showed in Figures 10.68 and 10.69. of the AL residuals fall in the interval [-5, 5] and are at sub-mas level. On the other side, almost all the residuals in AC () fall in the interval [-800,800]. The histogram in AC shows a peak around , which is related to the distribution of the residuals as a function of the G magnitude: for objects fainter than G=13, the errors in AC are large, while for objects brighter than G=13 the full 2-D window is transmitted and the accuracy in AL and AC are similar (even though the accuracy in AC are still larger).
The analysis at CCD-level and at transit level and interpretation of asteroid residuals is completely contained in Gaia Collaboration et al. (2018f).
