Description

Very simple test instrument for 3 examples from the suite of SasView_ components.
Select sample model with 'model_index':
1= SasView_barbell
3= SasView_bcc_paracrystal
47= SasView_parallelepiped

Examples

(Test cases in bold)

• Test: model_index=1 Ncount=1e5 par1=4 par2=1 par3=40 par4=20 par5=400 Detector: detector_I=605
• Test: model_index=3 Ncount=1e5 par1=220 par2=0.06 par3=40 par4=4 par5=1 Detector: detector_I=4.2
• Test: model_index=47 Ncount=1e5 par1=4 par2=2 par3=35 par4=75 par5=400 Detector: detector_I=297

Input parameters

Parameters in boldface are required; the others are optional.
