This is a simulation of a reflectometer installed on the cold moderator of the 16.667 Hz 
long pulse target station of the ESS. Source and moderator are described by the moderator 
description file 'EssLPTherm.src'.
By giving the Name 'ESS' in that file, the analytical function describing the wavelength 
and time dependence of the flux are chosen.

Gravity was included in the simulation.
