Example 1 - extracted from Madariaga, G., Z\'u\~niga, F.J., Paciorek, W.A. & Bocanegra, E.H. [(1990). Acta Cryst. B46, 620-628.] The meaning of _atom_site_occ_Fourier_param_id is given in the example of the ATOM_SITE_OCC_FOURIER category.

Definition

    	
   Data items in the ATOM_SITE_OCC_FOURIER_PARAM category record 
   details about the coefficients of the Fourier series used to 
   describe the occupational modulation of the atom sites in a
   modulated structure. The Fourier components are defined in the 
   category ATOM_SITE_OCC_FOURIER and are listed separately.
