The routine changes the neutron flux (weight) in order to match
a reference source table on disk. This file can be on format
(k[Angs-1],p), (omega[meV],p), (lambda[Angs],p) where p is the weight
A linear interpolation is performed during simulation.
This component should be placed after a source, in order to
simulate a real source.
EXAMPLE :
(xmin = -0.1, xmax = 0.1,
ymin = -0.1, ymax = 0.1,
file="source.flux",
options="")
With file "source.flux" beeing something like
# energy multiply
# [ meV flux_factor ]
0 1
2 1.2
10 1.5
100 1
