Comparison between Gaia DR2 and Gaia EDR3, from top to bottom, in the CAMD, in a G vs. distance diagram, and on the sky in galactic coordinates. Left: stars in Gaia DR2 not found in Gaia EDR3. Right: stars in Gaia EDR3 not in Gaia DR2. Upper and middle right panels: coloured with the ipd_ frac_multi_peak. This parameter, available in Gaia EDR3, provides the fraction of windows as percentage from 0 to 100 for which the detection algorithm has identified a “double peak”, meaning that it was probably a visually resolved double star (either just a visualdouble or a real binary).
