Behind The Spectrum fitting code
The Behind The Spectrum (BTS) fitting code is a python module designed to be a fully-automated multiple-component fitter for optically-thin spectra. The code is open-source. If the code is used in published work please cite Clarke et al. 2018, MNRAS, 479, 1722, which shows the first use of the code, as well as a description of the code's methodology and tests of the code's accuracy.
