A comparison of predicted planetary transit light curves as a function of stellar effective temperature. Left: average differences between synthetic planetary transit light curves computed using model stellar atmosphere CLIV and using best-fit quadratric limb-darkening laws as a function of effective temperature for the TESS band (top) and K band (bottom). Right: same as the left panels, but for the RMS difference of the light curves. For each effective temperature bin, there are models computed for four different gravities and five different masses.
