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.
