Average completeness of the survey considering the primary stars only (left panel), secondaries only (centre) and all starstogether (right). The colourmap is the same in all panels and indicates the average completeness level as a function of mass and semi-major axis for each sub-sample. The black contours show the number of stars from each subset around which companions of given masses and separations are detectable, and are therefore out of 27 stars for the left and middle panels, and out of 54 targets for the right panel.
