Theoretical Gaia detection rates of companions with a given mass and sma around GJ 832 as permitted by allowing a detection with PMa ∪ UEVA. White regions show the mass and sma for which the probability of detection of the companion is less than 10%; dark green regions show a probability of detection >99%; light green regions have intermediate probabilities. Individual maps for UEVA and PMa are shown in Fig. G.3.
