SplupsParser#

class fiasco.io.sources.SplupsParser(ion_filename, **kwargs)[source]#

Bases: GenericIonParser

Spline fits to scaled collisions strengths (denoted by upsilon) between energy levels as described in Burgess and Tully [BT92]. These files were used in CHIANTI versions prior to 8.0, and were replaced by .scups files in versions after that.

Notes

The number of spline points for the rates depends on the fit type, 5 points for type 6 fits and 9 points for type 2.
