**Definition:**

Unit-cell angles of the reported structure in degrees. The values of _refln_index_h, *_k, *_l must correspond to the cell defined by these values and _cell_length_a, *_b and *_c. The values of _diffrn_refln_index_h, *_k, *_l may not correspond to these values if a cell transformation took place following the measurement of the diffraction intensities. See also _diffrn_reflns_transf_matrix_.

The permitted range is 0.0 -> 180.0

Enumeration default: 90.0

**Type:** numb

**Category:** cell
