Since the local effective temperature and surface gravity vary across the surface of a tidally distorted binary star, the limb-darkening coefficient(s) used for computing local intensities also vary. We examine the effects of position-dependent limb-darkening on computed light curves. We use a modified version of the Wilson-Devinney light curve program, linked with the Van Hamme (1993) limb-darkening tables. Results are presented with graphs which compare light curves obtained with this method and those based on constant limb-darkening.
