Schematic representation of the analysis method used here. In step one, both the spectral and polarization events are extracted from the data. These are used to produce a spectrum (in count space) and a scattering angle distribution. Spectral parameters are picked from the provided priors and combined with the spectral response to produce a spectrum (again in count space) which is used together with the measured spectrum to calculate a likelihood. In parallel, these spectral parameters are, together with polarization parameters from a prior, provided to the polarization response in order to produce a scattering angle distribution. This is then used to calculate a likelihood using the measured distribution. Going through this process for different parameters in order to minimize the likelihood, a posterior distribution is produced for both the spectral and polarization parameters.
