Definition of LED direction spectra parameter structure, subtype-a. Version 1.2 Level(s): 3 Format(s): f30,f40,f50 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'.
