Galaxy Builder - Straightforward Population Synthesis SED Fitting

Galaxy Builder is a high-level IDL pipeline for performing customizable SED fitting on photometric data sets.

Details:

Although the astronomical community does not lack for SED fitting packages, here is another one. Galaxy builder is designed for highly customizable fitting of SED data, especially in the presence of limited data, variable S/N, or other limitations. It supports mid-IR, far-IR, and nonthermal radio emission as well as stellar emission using the standard BC03 population synthesis templates. As

Features:

• Entirely in IDL with no dependencies other than the GSFC library, making for straightforward installation.
• Produces a complete SED from UV to radio.
• Star-formation history parameterized fully analytically; straightforward input/output parameters.
• Automatic determination of Monte Carlo parameter uncertainties
• High-quality automated plotting

Limitations:

• Not yet carefully tested against other SED fitting codes
• Relatively slow (not suitable for 100+ targets)
• Occasional convergence difficulties
