XmlmmCIF equivalent: cell_measurement Data items in the CELL_MEASUREMENT category record details about the measurement of the crystallographic cell parameters. XmlmmCIF equivalent: cell_measurement/pressure The pressure in kilopascals at which the unit-cell parameters were measured (not the pressure used to synthesize the sample). XmlmmCIF equivalent: cell_measurement/pressure_esd The estimated standard deviation of _cell_measurement.pressure. XmlmmCIF equivalent: cell_measurement/radiation Description of the radiation used to measure the unit-cell data. See also _cell_measurement.wavelength. XmlmmCIF equivalent: cell_measurement/reflns_used The total number of reflections used to determine the unit cell. These reflections may be specified as CELL_MEASUREMENT_REFLN data items. XmlmmCIF equivalent: cell_measurement/temp The temperature in kelvins at which the unit-cell parameters were measured (not the temperature of synthesis). XmlmmCIF equivalent: cell_measurement/temp_esd The estimated standard deviation of _cell_measurement.temp. XmlmmCIF equivalent: cell_measurement/theta_max The maximum theta angle in degrees of reflections used to measure the unit cell. XmlmmCIF equivalent: cell_measurement/theta_min The minimum theta angle in degrees of reflections used to measure the unit cell. XmlmmCIF equivalent: cell_measurement/wavelength The wavelength in angstroms of the radiation used to measure the unit cell. If this is not specified, the wavelength is assumed to be that specified in the category DIFFRN_RADIATION_WAVELENGTH. XmlmmCIF equivalent: cell_measurement/entry_id This data item is a pointer to _entry.id in the ENTRY category.
