Alert level C DIFMX01_ALERT_2_C The maximum difference density is > 0.1*ZMAX*0.75 _refine_diff_density_max given = 1.471 Test value = 1.275
Author Response: The relatively high residual electron density peak is near the methoxy-O2 atom and is not in a chemically sensible position. The maximum and minimum residual electron density peaks of 1.47 and 0.46 e\%A^-3^, respectively, were located 0.85 \%A and 0.68 \%A from the O2 and Cl1 atoms, respectively.
DIFMX02_ALERT_1_C  The maximum difference density is > 0.1*ZMAX*0.75
            The relevant atom site should be identified.
