Dear Volker,
you don't have to care about the fact that distances are considered a histogram
- just enter them along with their estimated errors in the corresponding menu
option. We use e.g. d(Si-O)= 161+-1 pm, d(O-O )= 270+-5 pm for silicate tetra-
hedra. Then, there is an overall ponderation factor which puts the distance
histogram a weight relative to the intensity histogram(s). Try values from
1 to 100000, you should get it.
For more info, please specify the problem you have,
good luck!
