ABSTRACT. We have completed a new program that calculates both synthetic spectra and synthetic light curves for binary systems that contain a standard model optically thick accretion disk. Our initial model is physically and geometrically simple. It is capable of substantial elaboration. By basing both synthetic light curves and synthetic spectra on a single self-consistent model, we anticipate useful tests of systems for which both types of data are available. Alternatively, explicit simulations now become possible for systems for which only light curves or only spectra are available.

Subject headings: accretion, accretion disks; binaries: eclipsing; techniques: spectroscopic
