The SAXSNanodiscs McXtrace Component

A sample of monodisperse phospholipid bilayer nanodiscs in solution (water).

A component simulating the scattering from a box-shaped, thin solution (water) of monodisperse phospholipid bilayer nanodiscs.

Example: SAXSNanodiscs( xwidth = 0.01, yheight = 0.01, zdepth = 0.01, SampleToDetectorDistance = 0.48, DetectorRadius = 0.1 )

Parameters in boldface are required; the others are optional.
