Offsets in the positions of two nearby stars relative to that of the microlensed source (black) as determined from a difference imaging analysis of KMT data from the microlensing event in 2016. The two stars lie in the northwest and southeast quadrants of the zoom of Figure 1 from Vandorou et al. (2023). The analysis of the present work yields the offsets of these two stars at two epochs, i.e., 2018 (blue, NIRC2) and 2020 (red, OSIRIS). The northwest star is much closer to the microlensed source, suggesting that the two are associated. By contrast, Vandorou et al. (2023) assumed that the southeast star was associated with the microlensing event. Note that the black error bars reflect the precision of centroiding the source within the KMT difference images, whereas the blue and red error bars reflect the precision of transforming from the Keck images to the KMT reference image. As discussed in the text, we estimate the true centroiding errors to be ∼15 mas; for reference, we show ±15 mas error bars in yellow to the lower right of the plot.
