A plot of the level of systematic error in Gaia as a function of distance. The black line shows a 30 μas systematic uncertainty in Gaia DR3 estimated by Lindegren et al. (2021), which dominates the luminosity systematics at ∼600 and ∼1400 pc when the R _* uncertainties are at the systematic limits of 1.7% and 4.2%, respectively, marked as red dashed lines.
