WebApr 5, 2024 · Line/Spectrum Fitting. ¶. One of the primary tasks in spectroscopic analysis is fitting models of spectra. This concept is often applied mainly to line-fitting, but the same general approach applies to continuum fitting or even full-spectrum fitting. specutils provides conveniences that aim to leverage the general fitting framework of astropy ...
