Red Alert Alert Level A:
DIFF_019 Alert A _diffrn_standards_number is missing Number of standards used in measurement.
Author response: The data have been collected on an area detector.
DIFF_020  Alert A _diffrn_standards_interval_count and                          
          _diffrn_standards_interval_time are missing. Number of measurements   
          between standards or time (min) between standards.                    
Author response: The data have been collected on an area detector.
DIFF_022  Alert A _diffrn_standards_decay_% is missing                          
          Percentage decrease in standards intensity.                           
Author response: The data have been collected on an area detector.

Amber Alert Alert Level B:
ABSTM_02 Alert B The ratio of expected to reported Tmax/Tmin(RR') is < 0.75 Tmin and Tmax reported: 0.659 0.952 Tmin' and Tmax expected: 0.897 0.952 RR' = 0.735 Please check that your absorption correction is appropriate. General Notes
REFLT_03 From the CIF: _diffrn_reflns_theta_max 32.74 From the CIF: _reflns_number_total 1091 Count of symmetry unique reflns 650 Completeness (_total/calc) 167.85% TEST3: Check Friedels for noncentro structure Estimate of Friedel pairs measured 441 Fraction of Friedel pairs measured 0.678 Are heavy atom types Z>Si present yes Please check that the estimate of the number of Friedel pairs is correct. If it is not, please give the correct count in the _publ_section_exptl_refinement section of the submitted CIF.
3 Alert Level A = Potentially serious problem
1 Alert Level B = Potential problem
0 Alert Level C = Please check
