Description

Toy model used for testing various sample components for solution-SANS.

The following SANS samples are handled:
SANSSpheres               SAMPLE=0
SANSShells                SAMPLE=1
SANSCylinders             SAMPLE=2
SANSEllipticCylinders     SAMPLE=3
SANSLiposomes             SAMPLE=4
SANSNanodiscs             SAMPLE=5
SANSNanodiscsWithTags     SAMPLE=6
SANSPDB                   SAMPLE=7 (very slow, rather use SANSPDBFast)
SANSCurve                 SAMPLE=8 (inactivated)
SANSNanodiscsFast         SAMPLE=9
SANSNanodiscsWithTagsFast SAMPLE=10
SANSPDBFast               SAMPLE=11

Input parameters

Parameters in boldface are required; the others are optional.
