6410	C --------
6411	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
6412	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6413	C INTERVALS.
6414	C
6415	C METHOD.
6416	C -------
6417	C
6418	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6419	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6420	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6421	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6422	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
