6329	C --------
6330	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
6331	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6332	C INTERVALS.
6333	C
6334	C METHOD.
6335	C -------
6336	C
6337	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6338	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6339	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6340	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6341	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
