tardis.plasma.properties.rate_matrix_index module

class tardis.plasma.properties.rate_matrix_index.NLTEIndexHelper(plasma_parent, nlte_ionization_species=0, nlte_excitation_species=0)

Bases: ProcessingPlasmaProperty

calculate(levels, nlte_ionization_species, nlte_excitation_species)

Generates rate_matrix_index using levels and changing the last index(level) to “lte_ion” if that ion_number is treated in LTE or nebular, “nlte_ion” for NLTE ionization and keeps the levels for the rest.

Parameters

levelsMultiIndex

(Atomic number, Ion number, Level)

nlte_ionization_specieslist

List of tuples for (atomic number, ion number) which are treated in NLTE ionization.

Returns

MultiIndex
