Probability density functions of ruwe, UEVA, UEVA^1/3, and PMa, PMa² and PMa^2/3 are modeled for a companion with mass 100 M_J and sma=1 au around a system similar to GJ 832 (i.e., an M-type star at parallax of 200 mas). Modeled data are shown in the blue histograms, and normal or χ² laws are shown as red curves. The results of a Kolmogorov-Smirnov test statistics are shown in the legend.
