A user-oriented package for modeling stellar atmospheres
and for stellar spectroscopic diagnostics

Synspec is a general spectrum synthesis program. It assumes an existing model atmosphere, calculated previously with Tlusty or taken from the literature, for instance from the Kurucz grid of models. The opacity sources (continua, atomic and molecular lines) are fully specified by the user. An arbitrary stellar rotation and instrumental profile can be applied to the synthetic spectrum.

Synplot is a user-friendly IDL wrapper around Synspec. Synplot is keyword-driven and incorporates all the necessary plotting resources for spectral analyses.
