Item Description

the curve has to be weigthed taking into the account the number of independent asymmetric units (N). In that case the curve would be defined as sqrt(N)*3*sigma. This is the weighted factor used. If this weighted factor is always defined as 3*sqrt(N) then we only need to know the number of independent units N.
