The enhancements to the Wilson-Devinney code described earlier (see Milone et al., ApJS 79, 123, 1992 and Milone, ed., 'Light Curve Modeling of Eclipsing Binary Stars' 1993) have been extended to the 1993 version of the WD program and now involve the latest Kurucz atmospheres for a range of metallicities. Potentially all of Kurucz' models may be used to construct files of the ratio of the flux to blackbody curves for the passbands of interest, if the passband profiles are known. The version is called WD93K93. These improvements have also been extended to our simplex version, LC93KS, which permits a sweep of parameter space for deepest minimum and thus tests model uniqueness. Both codes now permit spot modeling although WD93K93 is restricted to 4 parameters on each of 2 spots. Future work will involve attempts to improve the convergence algorithms, global search capabilities, and efficiency. This work is being supported by Canadian NSERC and University of Calgary URGC Grants to EFM.
