6038	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6039	C INTERVALS.
6040	C
6041	C METHOD.
6042	C -------
6043	C
6044	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6045	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6046	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6047	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6048	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
