Description
Toy model used for testing various sample components for solution-SAXS. The following SAXS samples are handled: SAXSSpheres SAMPLE=0 SAXSShells SAMPLE=1 SAXSCylinders SAMPLE=2 SAXSEllipticCylinders SAMPLE=3 SAXSLiposomes SAMPLE=4 SAXSNanodiscs SAMPLE=5 SAXSNanodiscsWithTags SAMPLE=6 SAXSPDB SAMPLE=7 (very slow, rather use SAXSPDBFast) SAXSCurve SAMPLE=8 (inactivated) SAXSNanodiscsFast SAMPLE=9 SAXSNanodiscsWithTagsFast SAMPLE=10 SAXSPDBFast SAMPLE=11
