5993	C --------
5994	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
5995	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
5996	C INTERVALS.
5997	C
5998	C METHOD.
5999	C -------
6000	C
6001	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6002	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6003	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6004	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6005	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
