AbsorptionSpectrum.add_line(label, field_name, wavelength, f_value, gamma, atomic_mass, label_threshold=None)[source]¶

Add an absorption line to the list of lines included in the spectrum.

Parameters:	label : string label for the line. field_name : string field name from ray data for column densities. wavelength : float line rest wavelength in angstroms. f_value : float line f-value. gamma : float line gamme value. atomic_mass : float mass of atom in amu.
