The best-fit quadratic limb-darkening parameters (not following the reparameterization detailed in D. M. Kipping 2013) for the individual channels (black) and binned to 0.2 μm for clarity (blue). The expected limb-darkening parameters based on Z. Magic et al. (2015; purple), R.-L. Kurucz (1993; red), and N. Kostogryz et al. (2023; orange) models are also shown. While the overall shape of the best-fit limb-darkening parameters is in agreement for the bluer <4.5 μm, within the error bars, there is an offset and significant scatter in some of the channels.
