Level#

class fiasco.Level(index, elvlc)[source]#

An object for holding atomic energy level data from CHIANTI.

Warning

This is not meant to be instantiated directly, but rather accessed by indexing a fiasco.Ion object.

Parameters:

index (int) – The index of the energy level.
elvlc (DataIndexer) – Pointer to the energy level information for a given ion in the CHIANTI database.

Attributes Summary

`configuration`	Label denoting the electronic configuration of the level
`energy`	Energy of level.
`is_observed`	True if the energy of the level is from laboratory measurements.
`level`	Index of the level.
`multiplicity`	The multiplicity of the level
`orbital_angular_momentum_label`	The orbital angular momentum number \(L\).
`total_angular_momentum`	The total angular momentum number \(J\).

Attributes Documentation

energy#: Energy of level. Defaults to observed energy and falls back to theoretical energy if no measured energy is available.

is_observed#: True if the energy of the level is from laboratory measurements.
