Enumeration default: 0.0
The occupational distortion of a given atom or rigid group is usually parameterized by Fourier series. Each term of the series commonly adopts two different representations: the sine-cosine form, Pc cos(2\p k r)+Ps sin(2\p k r); and the modulus-argument form, |P| cos(2\p k r+\d); where k is the wave vector of the term and r is the atomic average position. _atom_site_occ_Fourier_param_sin is the sine coefficient (Ps) corresponding to the Fourier term defined by _atom_site_occ_Fourier_atom_site_label, and _atom_site_occ_Fourier_wave_vector_seq_id.
