Alert level A DIFF020_ALERT_1_A _diffrn_standards_interval_count and _diffrn_standards_interval_time are missing. Number of measurements between standards or time (min) between standards. DIFF022_ALERT_1_A _diffrn_standards_decay_% is missing Percentage decrease in standards intensity.
Alert level B PLAT019_ALERT_1_B Check _diffrn_measured_fraction_theta_full/_max 0.972
Author Response: On account of the twinning, some reflections were rejected during scaling. Because of this, the completeness for the full data set did turn out to be higher than for the theta < 25 degree data.
