This is a Python port of the SED fitter from Robitaille et al., 2007, ApJS 169 328. It replaces the original Fortran code which can be found here.
At this stage, it should be used cautiously as it is still beta-quality software and may contain bugs. Please make sure that you verify your results using an independent method if at all possible.
