pyrfu.pyrf.c_4_k module#
- pyrfu.pyrf.c_4_k.c_4_k(r_list: Sequence[DataArray]) Sequence[DataArray][source]#
Calculates reciprocal vectors in barycentric coordinates.
- Parameters:
r_list (list of DataArray) – Position of the spacecrafts.
- Returns:
k_list – Reciprocal vectors in barycentric coordinates.
- Return type:
list of DataArray
Notes
The units of reciprocal vectors are the same as [1/r].
