CheckCIF-CELLT01

PROC-NAME: CELLT01 Type_1

PURPOSE: To check that _cell_measurement_theta_min is less than _cell_measurement_theta_max.

PROCEDURE:

TEST

IF _cell_measurement_theta_min >= _cell_measurement_theta_max

issue ALERT A

        "Alert A The minimum theta value cannot exceed the maximum value."

        The minimum theta value cannot exceed the maximum value. Either there is a typographical error or the values under _cell_measurement_theta_min and _cell_measurement_theta_max have accidentally been reversed.

(http://journals.iucr.org/services/cif/checking/CELLT_01.html)

目的：检查单胞测试最小θ角(_cell_measurement_theta_min)是否小于单胞测试最大θ角(_cell_measurement_theta_max)。

若_cell_measurement_theta_min大于等于_cell_measurement_theta_max，发布A类警告

        "Alert A The minimum theta value cannot exceed the maximum value."

        单胞测试最小θ角不能超过单胞测试最大θ角。要么存在误排，要么“_cell_measurement_theta_min”项和“_cell_measurement_theta_max”项的数值颠倒了。

例：CELLT01_ALERT_1_A The minimum theta value cannot exceed the maximum value.

Value of theta(min) given = 27.050 Value of theta(max) given = 1.190

解决策略：可能是误将这两个数值填反了，将其改正即可。
