qspec.cast_hyper_const  (  hyper_const  )[source]

Preprocess the hyperfine-structure constants.

Parameters:

hyper_constarray_like

The hyperfine-structure constants. Currently, constants up to the magnetic octupole order are supported (A, B, C). If 'hyper_const' is a scalar, it is assumed to be the constant A and the other orders are 0 (MHz).

Returns:

outndarray

The hyperfine-structure constants as a 3d-vector.
