Fraction of the Gaia EDR3 sources that are filtered out by the parallax cutoff as a function of the source magnitude. The blue bars indicate the fraction of sources without a parallax in Gaia EDR3, while the orange bars represent the fraction of sources for which the accuracy of the parallax is less than 3σ. The values given at the top indicate the total number of Gaia EDR3 sources in the magnitude bin.
