Abstract We summarize recent improvements to a version of the Wilson-Devinney program that is widely used for the analysis of eclipsing binary data, and we describe the new WD95 program. WD95 contains the University of Calgary version of the Wilson-Devinney code, which supports the use of the Kurucz atmo-sphere models; it provides options to use multiple epoch data and multiwavelength synoptic passbands. The WD95 program contains an improved input/output interface, simplex algorithms for initial searches and tests, and versions of Wilson-Devinney DC and LC programs and options to switch to automatic di†erential corrections or a damped least-squares solver using normal equations that are modiÐed as per the Levenberg-Marquardt scheme. This paper describes some tests of the damped least-squares solver with simulated data.
