+This section contains the probability distribution ($P(r)$) from SAXS
+measurements to be used as restraints through introduction of a maximum-likelihood term.

+NSAXS specified in the first data record. Each line contains the position

+The distance-distribution values do not need to be input in normalized form.
+Normalization is carried out automatically. It should be noted that neither 
+probabilities nor distances can be zero; otherwise the calculations will crash.
+Therefore, entries with zeros must be eliminated from the data.
