Variability distribution as a function of the G magnitude for 1 806 185 593 sources from Gaia DR3. The red line indicates our B-spline model that tracks the mean location of non-variable sources. We note that for G < 13, the photometry is affected by the gating and windowing system onboard Gaia. We indicate the approximate G magnitudes of the eleven gates with the dashed gray lines and the three window class changes resulting in overall offsets in the photometric calibration (details in Riello et al. 2021). Between these positions, the configuration affects the photometry in various manners, generating apparent wiggles and discontinuities. In DR3, the reported uncertainties include an additional calibration error on a single measurement of 2mmag corresponding to the apparent floor (log₁₀𝑔_var 2.7) at the bright end.
