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.

Examples

(Test cases in bold)

• Test: Test_source_spectra.instr flag4d=0 E0=12.4 dE=0.001 stemx=sp8LU_x stemy=sp8LU_y Detector: psd2_I=1.42775e+11
• Test: Test_source_spectra.instr flag4d=1 E0=12.4 dE=0.001 stem4d=sp8LU_xy Detector: psd2_I=3.53418e-06

Input parameters

Parameters in boldface are required; the others are optional.
