A sample of monodisperse phospholipid bilayer nanodiscs in solution (water).
Author: Martin Cramer Pedersen (mcpe@nbi.dk)
Origin: KU-Science
Date: October 17, 2012
A component very similar to EmptyNanodiscs.comp - however, the scattering profile is only computed once, and linear interpolation is the used to simulate the instrument.
Parameters in boldface are required; the others are optional.
