The program Denzo-SMN (Otwinowski & Minor, 1997) uses a scaling
algorithm (Fox & Holmes, 1966) which effectively corrects for
absorption effects. High redundancy data were used in the scaling
program hence 'multi-scan' code word was used. No transmission
coefficients are available from the program (only scale factors
for each frame). The transmission factors in the experimental table
are calculated from the 'size' command in the SHELXL-97 input file.
