Left-hand-side panels: configuration of rejected double stars leading either to a single local maximum (i.e., rejected unresolved double stars; top panel; 4631 objects), or to a local maximum for both components individually (i.e., rejected secondary components of resolved double stars; bottom panel; 13 376 objects) for the functional-baseline rejection parameters. Right-hand-side panels: orientation, in along- versus across-scan coordinates, of rejected objects leading either to a single local maximum (top panel), or to two local maxima (bottom panel). The dots represent the orientation of the secondary components with respect to their primary components, which are situated at the origin. The lines denote the CCD pixel grid; Gaia’s detection is based on SM samples, composed of 2 × 2-binned pixels.
