- specutils.fitting.find_lines_threshold(spectrum, noise_factor=1)¶
Find the emission and absorption lines in a spectrum. The method here is based on deviations larger than the spectrum’s uncertainty (converted to standard deviation if in another representation) by the
This method only works with continuum-subtracted spectra and the uncertainty must be defined on the spectrum. To add the uncertainty, one could use
noise_region_uncertaintyto add the uncertainty.
