spectrally independent

    1.1  COEFFICIENTS FOR TWO SPECTRAL INTERVALS
          ---------------------------------------

DERIVED FROM HITRAN APRIL 1992 with LOWTRAN P AND T SCALING H2O: Pref=1000hPa, Tref=296K, Pdep=0.9 UMG: Pref=1000hPa, Tref=296K, Pdep=0.75 (CO2+N2O+CO+CH4+O2) O3 : unchanged in interval 1, from HITRAN 92 in interval 4

1st spectral interval: U.V. and Visible (0.25 - 0.69 Micron)

Near-Infrared (0.69 - 4.0 Microns) is not sub-divided

0.68 - 4.00 Micron
