LOOK project contour plots. Top row: 2024 January 4 (MJD 60313.8750614) i-filter LOOK observation of 2023 RN3 (left) and a nearby background star (right). Center row: corresponding contour plots of the PSFs of 2023 RN3 (left) and the same background star (right). Bottom: radial profile of 2023 RN3 (gray circles) compared to mean radial profile (black line) and range of profiles (gray shaded) of 10 nearby field stars from 2024 January 4 i-filter LOOK observation, plotting instrumental surface brightness (in units of mag arcsec−2) normalized to the peak brightness of 2023 RN3 vs. radial distance from the PSF centroid.
