Special details top
Experimental. The program DENZO-SMN (Otwinowski & Minor, 1997) uses a scaling algorithm
[Fox, G. C. & Holmes, K. C. (1966). Acta Cryst. 20, 886–891] which
effectively corrects for absorption effects. High redundancy data were used in
the scaling program, hence the `multi-scan' code word was used. No
transmission coefficients are available from the program (only scale factors
for each frame). The scale factors in the experimental table are calculated
from the `size' command in the SHELXL97 input file. |
