Often, you want to plot only a certain component of a field or tensor field. You use a statement like:
tensor_bra 0 1 0 tensor_ket 0 0 1to select the yz component (in cartesian coordinates) of a tensor. The ``tensor'' input is also used for specifying the alignment of the external B-field for plotting purposes.
tensor_bra 1 0 0 tensor_ket 1 0 0
