Fitted linear limb darkening coefficient for V1298 Tau from the HST and JWST transit observations of V1298 Tau b (yellow data points with red 1σ error bars). The JWST limb darkening coefficients are measured at a higher spectral resolution compared to HST (by a factor of ∼10), which is why the JWST error bars are larger compared to HST. The continuous black curve is from a linear limb darkening model generated using ExoTiC-LD (D. Grant & H. Wakeford 2024) computed for a K1-type main-sequence star. The modeled linear limb darkening coefficients are found to be significantly smaller than the observed values, but the difference gets smaller at longer wavelengths.
