We have produced a large grid of 2-D radiation transfer models for Young Stellar Objects (YSOs). We developed a tool that fits observed spectral energy distributions (SEDs) using models from the grid. Our grid includes stellar atmosphere models and a small set of evolved star spectra. The fitter automatically shows the uniqueness (or lack thereof) of a fit by presenting all good models within a specified chi-squared fit. A statistical algorithm estimates the best fit parameters from the set of good fits. The fitter is currently designed to work with data taken in broadband filters, such as the Spitzer IRAC and MIPS filters, and any others that a user provides. The fitter is optimized, and can fit large sets of data in a short amount of time. We request funds to expand the grid of models and to make the grid and fitter publicly available by web access. We will run a "second" generation grid of YSO models. These new models will include such improvements as 3-D clumpy models, PAH emission, and external radiation fields. We will also expand the stellar atmosphere and evolved star grid. This tool will be applicable for users analyzing large and small datasets on star formation regions as well as stellar populations and Galactic structure in the Galaxy and other nearby galaxies.
