- Author: Martin Cramer Pedersen (mcpe@nbi.dk)
- Origin: KU-Science

## Description

    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.

## Input parameters

Parameters in boldface are required; the others are optional.
