 Alert Level C:



DIFMX_01  Alert C The maximum difference density is > 0.1*ZMAX*0.75             
          _refine_diff_density_max given =      0.707                           
          Test value =      0.600                                               

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