Abstract

The determination or estimation of physical parameters from eclipsing binary light curves and/or radial velocity curves is an inverse problem and can be formulated as a nonlinear least-squares problem. It is solved by optimizing the agreement between the calculated light and the observed light curve. The parameter vector x corresponding to minimum deviation is the system solution, and the calculated light curve produced from it is said to be the best fit to the data. A measure of the deviation is the weighted sum of the squared residuals.
