5982	C --------
5983	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
5984	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
5985	C INTERVALS.
5986	C
5987	C METHOD.
5988	C -------
5989	C
5990	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
5991	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
5992	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
5993	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
5994	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
