 Alert Level A:



ABSTM_02  Alert A Crystal and compound unsuitable for non-numerical             
          corrections. Product of mu and tmid > 3.0                             
           Value of mu given =    39.976 tmid =     0.160

Author response: The sample used for the experiment was a ten micron flake from the bulk sample. The equitorial edges were not natural faces. An analytical face correction using approximate faces and distances in Sheldrick's XPREP did not provide as good a correction (based on R(int)) as did the emperical correction from SADABS. The volume of the sample could have been reduced, but this would have prevented the collection of high resolution data.


 Alert Level B:
