Comparison of the star positions derived from the close companion and those obtained by our fitting approach (negative and positive 2D Gaussian fitting labeled NP2DG in the figure). The small top and side panels show the kernel density estimators (KDE) for the X- and Y-axes, respectively. The grid represent pixels, and the colored cross corresponds to the typical uncertainty. The contour lines enclose the areas containing 95.5, 68.5, 50, 30, 10, and 1% of the sample with respect to the maximum of the distribution.
