6404	C --------
6405	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
6406	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6407	C INTERVALS.
6408	C
6409	C METHOD.
6410	C -------
6411	C
6412	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6413	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6414	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6415	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6416	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
