Description

A test instrument to compare sources and check they provide the valid
sprectrum and intensity. It shows that the first 4 flat sources are equivalent,
the 2 Maxwellian sources as well.

WARNING: Result of test no. 1 for Source_adapt.comp is not correct if MPI is used, as
that source component does not support MPI.

Example: source=1 Detector: m1_I=9.97273e+11

Examples

(Test cases in bold)

• Test: source=2 Detector: m1_I=9.48467e+11
• Test: source=3 Detector: m1_I=9.96553e+11
• Test: source=4 Detector: m1_I=9.966e+11
• Test: source=5 Detector: m1_I=2.4279e+11
• Test: source=6 Detector: m1_I=2.42284e+11
• Test: source=7 Detector: m1_I=2.28139e+13
• Test: source=8 Detector: m1_I=5.0787e+13

Input parameters

Parameters in boldface are required; the others are optional.
