Figure caption: The plots show the correlation between the injected and retrieved values of the companion injections. The left and right panels show the separation and contrast values, respectively. And the top and bottom panels show the injections into calibrated data (the same as in Figure 5) and Gaussian distributions (similar to Figure 4), respectively. The injection tests are at the same contrast and separation values as in Figure 5, with their respective (color-coded) test numbers for tests with k-values ≥5σ (see Table 4). The error bars on the plot points are the 1σ errors from the best fit. The retrieved values in the top panel are consistent with the injection values within 1σ (the error bars overlap with the 1:1 straight line, shown in gray), where the injections are into calibrated data. This is also true in the bottom panel, where the injections are into Gaussian distributions of closure phases and squared visibilities, equivalent to the method used to produce Figure 4 and discussed in Section 4.3.
