W matrices

The elements of the W matrices corresponding to each one of the subsystems are listed in a loop with the following data items:
Subsystem code
_cell_subsystem_code
For composite structures a code that links the anisotropic atom parameters of a given atom or rigid group site to the subsystem to which the site belongs.

Subsystem descritpion
_cell_subsystem_description
The description of the subsystem.

Elements of the W matrx
_cell_subsystem_matrix_W_i_j The elements W(i,j) of the matrix W for the current subsystem.
