The nELBE data sets have been selected in the energy range with sufficient counting statistics.
As the beam intensity and measurement time and target thicknesses varied, this is different for some measurements.
There are two small regions not measurable, as the gamma flash caused reflexions in the signal cables, that overlapped
with the neutron signals.
 
Every data set e.g. oxygen_nELBE_exfor.grf) is a text-file.
It has 13 columns: 
Column 1-4 are (index number, Time-of-flight(ns), energy limits of the tof channel)
Column 5 is the neutron kinetic energy in MeV (center energy of each tof channel)
Column 6 Transmission
Column 7 Statistical Uncertainty of Transmission 
Column 8 Total cross section (barn) 
Column 9 Statistical Uncertainty of total cross section
Column 10,11 Time-of-flight spectra (counts) target in/out (summed over all runs, rebinned to 20 TDC channels, dead time corrected, but with background)
Column 12,13 Ratio of background/total counts target in/out  (summed over all runs, rebinned to 20 TDC channels, dead time corrected)

I am happy to provide additional information or answer questions.
