Errors in selected light curve parameters from least-squares fits to light curves generated from limb darkening profiles from the STAGGER-grid, as a function of radius ratio, p, for three different algorithms. From left to right panels: ellc light curve model with the power-2 limb-darkening law; Mandel & Agol algorithm for the quadratic limb-darkening law; qpower2 algorithm. Results are shown for three values of the impact parameter, as follows: b = 0.3 – solid green line, b = 0.6 – dotted blue line, b = 0.9 – dashed cyan line.
