6348	C --------
6349	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
6350	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6351	C INTERVALS.
6352	C
6353	C METHOD.
6354	C -------
6355	C
6356	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6357	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6358	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6359	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6360	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
