 Parameters for level-3 LED direction spectra

 Version: 1.0

 DESCRIPTION

   The level-3 LED direction spectra data consists of records with proton and
   he4  energy channels (16 for protons and 8 for he4) for each of the seven
   LED D1-detectors (D1i). The parameter data reflects the format of the
   measurement records by providing energy values (Emin, Emax and Enom) for
   each measurement channel, as well as the GdE and efficiency paramaters for
   each channel of each D1i detector.

   The thin D1-detectors (D11 and D16) cover the whole energy range while the
   thick detector (D12, D13, D14, D15 and D17) measurements are recorded only
   from energies of about 3 MeV/n upwards. In order to streamline the direction
   measurement handling, the level-3 data is recorded with equal number of
   channels for each detector, but with the first channels (6 for proton and
   3 for he4) empty. This is reflected in the corresponding tabulated GdE and
   Eff values of 0.0 below.


 INTENDED USE

   The data is primarily intended to be used by the 'eint_leddir' IDL-program
   when combining the energy channels of the level-3 LED direction spectra.
   The 'eint_leddir' is itself normally called by the 'ged_l3_ledDirSpectra'-
   program.


 NOTES

   The efficiency parameters are currently not used but are provided as a
   future option for analysis development.
