Contrast curves for TOI-1143 showing the detection limit of NESSI speckle imaging in the 562 nm (blue curve) and 832 nm filters (red curve). The star symbol indicates the separation and contrast of the detected companion. A reconstructed image for each filter is shown in the upper right, with TOI-1143 in the center of the field. The companion appears as a pair of close-by sources lying roughly north and south of TOI-1143. The double image is due to an ambiguity in the image reconstruction. These images are oriented with north at the top and east to the left.
