Multi-spectrum Analysis Tool for Spectroscopy (MATS)

The purpose of the MATS project is to develop a NIST-based multi-spectrum fitting tool for spectroscopic data that allows the flexibility to test and adapt to experimental/data-driven needs. This software allows for the use of several commonly used spectroscopic line profiles (Voigt, Nelkin-Ghatak, speed-dependent Voigt, speed-dependent Nelkin-Ghatak, and Hartmann-Tran) and allows for pressure, temperature, and composition constraints to be imposed on solutions. In addition to fitting experimental spectra, MATS can generate simulated spectra, which allows for its use as an error analysis tool. The tool uses existing python applications such as the HITRAN Application Programming Interface (HAPI) and LMFit as the engine for spectral fitting.
