Maximum deviation between the observed sample with N = 54 and a synthetic sample containing N′ = 10 000 objects, with the companion mass being distributed as a Gaussian with a mean mass as given by the abscissa. The blue dotted line is drawn at D^∗ = 0.2628: all simulations with a higher value of the estimator can be rejected at the 99.9% level as being drawn from the same population as the observed distribution. The magenta dashed line is drawn at D^∗ = 0.1274 and provide a 1σ estimate of the allowed parameter range, while the red solid line is drawn at D^∗ = 0.0506.
