Parallax uncertainties in Gaia DR2 (dots) as a function of G compared to the uncertainties quoted for Gaia DR1 (colour scale) and the expected end-of-mission parallax performance (solid line), as predicted after the commissioning of Gaia. Note how the performance for Gaia DR2 is still limited by calibration uncertainties for sources brighter than G ~ 14.
