The energy-sensitive monitor
The component E_monitor resembles TOF_monitor to a very large extent. Only this monitor is sensitive to the neutron energy, which in binned in nE bins between \(E_\textrm {min}\) and \(E_\textrm {max}\) (in meV).
The output parameters from E_monitor are the total counts, and a file with 1-dimensional data vs. \(E\), similar to TOF_monitor.
