 Alert Level C:



DIFMX_01  Alert C The maximum difference density is > 0.1*ZMAX*0.75             
          _refine_diff_density_max given =      0.954

DIFMX_02  Alert C The minimum difference density is > 0.1*ZMAX*0.75             
          The relevant atom site should be identified.                          

General Notes



FORMU_01  There is a discrepancy between the atom counts in the                 
          _chemical_formula_sum and _chemical_formula_moiety. This is           
          usually due to the moiety formula being in the wrong format.          
          Atom count from _chemical_formula_sum:   C41 H38 Na2 O9               
          Atom count from _chemical_formula_moiety:C79 H68 Na2 O17
