Large-angle angular covariance of the Gaia EDR3 parallaxes.Left panel: 0°–20° separation range with the quasar data in 1° bins using either ϖ (blue asterisks) or ϖ_c (black error bars), the linear fit to the quasar corrected data in the 5°–40° separation range (green line), and the analytical fit to the LMC data (red line). The error bars associated with the quasar ϖ data are not shown, but they are similar to those for ϖ_c. Right panel: full 0°–180° separation range and includes the total quasar+LMC model.
