	6359	C --------
	6360	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
	6361	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
	6362	C INTERVALS.
	6363	C
	6364	C METHOD.
	6365	C -------
	6366	C
	6367	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
	6368	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
	6369	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
	6370	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
	6371	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
