/*******************************************************************************
* McStas instrument definition URL=http://www.mcstas.org
*
* Instrument: Test_Guides
*
* %Identification
* Written by: E. Farhi [farhi@ill.fr]
* Date: Sept 1st, 2008
* Origin: ILL
* %INSTRUMENT_SITE: Tests_optics
*
* Cross comparison of Guide components
*
* %Description
* Cross comparison of Guide components, using McStas and
* contributed components. It shows that all implementations are equivalent,
* except the Guide_honeycomb which has a different geometry.
*
* %Example: Guide=1 Detector: Monitor2_xy_I=0.00726875
* %Example: Guide=2 Detector: Monitor2_xy_I=0.00725213
* %Example: Guide=3 Detector: Monitor2_xy_I=0.00727304
* %Example: Guide=4 Detector: Monitor2_xy_I=0.00721742
* %Example: Guide=5 Detector: Monitor2_xy_I=0.00721742
* %Example: Guide=6 Detector: Monitor2_xy_I=0.00721742
* %Example: Guide=7 Detector: Monitor2_xy_I=0.00724912
* %Example: Guide=8 Detector: Monitor2_xy_I=0.00683072
* %Example: Guide=9 Detector: Monitor2_xy_I=0.00724912
*
* %Parameters
* Guide: [1] Choice of Guide component to test, with 1=Guide, 2=Guide_channeled, 3=Guide_gravity, 4=Guide_wavy, 5=Guide_curved 6=Elliptic_guide_gravity 7=Guide_honeycomb
