[ascl:2409.007] Stardust: Composite template fitting software

Stardust extracts galaxy properties by fitting their multiwavelength data to a set of linearly combined templates. This Python package brings three different families of templates together: 1.) UV+Optical emission from dust unobscured stellar light; 2.) AGN heated dust in the MIR; and 3.) IR dust reprocessed stellar light in the NIR-FIR. Stardust's template fitting does not rely on energy balance. As a result, the total luminosity of dust obscured and dust unobscured stellar light do not rely on each other, and it is possible to fit objects such as SMGs where the energy balance approach might not be applicable.
