The separation and relative magnitude of all detected candidate companions. Also plotted is the 5σ detection limit of our observations of WASP-7, typical of our data. Note that the sensitivity of some observations was better at low separation (the closest companion, that to WASP-2, was detected in exceptionally good seeing), and that the lower limit on sensitivity at large separations varied with target brightness and atmospheric conditions.
