pyrfu.pyrf.c_4_k module#

pyrfu.pyrf.c_4_k.c_4_k(r_list)[source]#

Calculates reciprocal vectors in barycentric coordinates.

Parameters:: r_list (list of xarray.DataArray) – Position of the spacecrafts.
Returns:: k_list – Reciprocal vectors in barycentric coordinates.
Return type:: list of xarray.DataArray

Notes

The units of reciprocal vectors are the same as [1/r].
