SSOF models are created by element-wise multiplying models for the telluric and stellar spectra and then multiplying by a a sparse matrix which approximates a convolution with the instrumental LSF. This flexibility is instrument-agnostic, and results in a robust, automated separation of telluric and stellar components.
