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
