/*******************************************************************************
* McXtrace instrument definition URL=http://www.mcxtrace.org
*
* Instrument: Test_source_spectra
*
* %Identification
* Written by: Erik B Knudsen (erkn@fysik.dtu.dk)
* Date: Aug. 10th, 2014
* Origin: DTU Physics
* Release: McXtrace 1.2
* Version: 1.0
* %INSTRUMENT_SITE: Tests_sources
*
* Test instrument for the Source_spectra component
*
* %Description
* A unit test instrument for the Source component that can take input from a SPECTRA-simulation
* of an undulator/wiggler etc. and input it into McXtrace.
*
* %Example: Test_source_spectra.instr flag4d=0 E0=12.4 dE=0.001 stemx=sp8LU_x stemy=sp8LU_y Detector: psd2_I=1.42775e+11
* %Example: Test_source_spectra.instr flag4d=1 E0=12.4 dE=0.001 stem4d=sp8LU_xy Detector: psd2_I=3.53418e-06
*
*
* %Parameters
* E0: [keV] Central wavelength for sampling
* dE: [keV] Halfwidth of sampleing window (in energy)
* stemx: [ ] Filename stem for the x-projection data files coming from SPECTRA.
* stemy: [ ] Filename stem for the y-projection data files coming from SPECTRA
* stem4d: [ ] Filename stem for 4D-datafiles from SPECTRA.
* flag4d: [ ] If zero use projection datafiles, else use 4D.
*
* %End
