 TledDirSpectraPara_a::
    CO_SYS   : STRING[3]      Coordinate system of the D1-directions
    CO_TYPE  : STRING[3]      Coordinate type of the D1-directions
    D1_DIR   : FLOAT[2,7]     Direction angles of the D1-detectors
    P_EMIN   : FLOAT[16,7]    Minimum energies for the protons ([E-channel,D1-detector])
    P_EMAX   : FLOAT[16,7]    Maximum energies for the protons
    P_ENOM   : FLOAT[16,7]    Nominal energies for the protons
    P_GDE    : FLOAT[16,7]    GdE values for the protons
    P_EFF    : FLOAT[16,7]    Effectivity coefficients for the protons
    HE4_EMIN : FLOAT[8,7]     Minimum energies for the he4
    HE4_EMAX : FLOAT[8,7]     Maximum energies for the he4
    HE4_ENOM : FLOAT[8,7]     Nominal energies for the he4
    HE4_GDE  : FLOAT[8,7]     GdE values for the he4
    HE4_EFF  : FLOAT[8,7]     Effectivity coefficients for the he4


 NOTE-1: There are 16 proton and 8 helium channels in the level-3 LED direction spectra
         data.  The thin D1-detectors (D11 and D16) cover the whole energy range, but
         the lowest channels (0-5 for protons and 0-2 for he4) of the thick D1-detectors
         (D12, D13, D14, D15 and D17) contain no data.

 NOTE-2: The data values for the structure fields are intended to be read from the
         parameter file 'lev3_ledDirSpectraPara', using the IDL program
         'read_lev3_ledDirSpectraPara'.
