Alert level C PLAT094_ALERT_2_C Ratio of Maximum / Minimum Residual Density .... 2.58
Alert level G REFLT03_ALERT_4_G 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.
