Abstract

Abstract SPARTAN [Spectroscopic And photometRic fitting Tool for Astronomical aNalysis] is a tool designed to perform the fitting of galaxy observations either using photometry and low resolution spectroscopy separately or simultaneously. Based on a grid search χ 2 fitting method, SPARTAN was tailored to UV-to-NIR data and designed for well calibrated data. The first version of this tool allows the use of the low resolution models of Bruzual & Charlot (2003) and include the treatment of the intergalactic medium as a free parameter. It has been designed to be an user-friendly environment where people do not need to know how to code to perform the fit. SPARTAN includes everything needed to perform the fit, from the galaxy models creation, to the visualization of the results through the graphical interface. SPARTAN is a fully open source software made with Python 3. It is published under the GNU general public license (v3) and is available in a Github repository. It can be installed directly from the python official repository (pypi) and the documentation is available through a github repository.
