Test case for an layered detector shell instrument to provide quick overview of resolution per pixel.
Set up to be run in McStas -> Mantid mode, refer to manual for details on execution.
Simulates desired divergence by adjusting moderator size.
Considers only in-plane (xwidth) factors, sets yheight as 1 cm.
For an example on how to analyze the data, see the 'Onion_analyzerScript.py' available at
Acceptable statistics can be achieved by running the simulation with 1E7 neutrons (output file: ~400MB)
Parameters in boldface are required;
the others are optional.
