Test of the ESS-2015 moderator model with updated component ESS_moderator.comp .
Author: Jan Saroun (firstname.lastname@example.org)
Origin: NPI Rez
Measures flux projected on a 1cm^2 target at 100 m,
The beamline origin is centered at the nearest cross point between cold and thermal moderators.
Accepts negative port angle. Default is -55 deg corresponding to the assumed BEER position (port 2).
Records spatial and time distributions at 0.3 m from the beamline origin and wavelength distribution
behind the target slit.
Parameters in boldface are required;
the others are optional.
