 Alert Level A:



PLAT_113  Alert A ADDSYM Suggests Possible Pseudo/New Spacegroup       C2/m

Author response: The C-centring is only approximate, as can be seen from an inspection of the reflection intensities, and in Fig. 2.


 Alert Level B:



PLAT_110  Alert B ADDSYM Detects Potential Lattice Centering or Halving   ?

Author response: see above


 Alert Level C:



ABSTM_02  Alert C The ratio of Tmax/Tmin expected RT(exp) is > 1.10             
          Absorption corrections should be applied.                             
          Tmin and Tmax expected:      0.868     0.956
