_refine.ls_abs_structure_Rogers

Name:
'_refine.ls_abs_structure_Rogers'

Definition:

   The measure of absolute structure (enantiomorph or polarity) as
   defined by Rogers.


   The value must lie in the 99.97% Gaussian confidence interval
   -1 -3u =< \h =< 1 + 3u and a standard uncertainty (estimated
   standard deviation) u must be supplied. The item range of
   [-1.0, 1.0] is correctly interpreted as meaning
   (-1.0 - 3u) =< \h =< (1.0 + 3u).
