'_geom_angle_publ_flag' value 'Y' changed to 'y' according to the
built-in table from CIF Core dictionary named 'cif_core.dic' version
2.4.1 from 2010-06-29 (115 times).

'_geom_angle_publ_flag' value 'N'
changed to 'n' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (150
times).
