64!     The array KA contains absorption coefs at the 16 chosen g-values
65!     for a range of pressure levels> ~100mb, temperatures, and binary
66!     species parameters (see taumol.f for definition).  The first
67!     index in the array, JS, runs from 1 to 9, and corresponds to
68!     different values of the binary species parameter.  For instance,
69!     JS=1 refers to dry air, JS = 2 corresponds to the paramter value 1/8,
70!     JS = 3 corresponds to the parameter value 2/8, etc.  The second index
71!     in the array, JT, which runs from 1 to 5, corresponds to different
72!     temperatures.  More specifically, JT = 3 means that the data are for
73!     the reference temperature TREF for this  pressure level, JT = 2 refers
74!     to TREF-15, JT = 1 is for TREF-30, JT = 4 is for TREF+15, and JT = 5
75!     is for TREF+30.  The third index, JP, runs from 1 to 13 and refers
76!     to the JPth reference pressure level (see taumol.f for these levels
77!     in mb).  The fourth index, IG, goes from 1 to 16, and indicates
78!     which g-interval the absorption coefficients are for.

82!     The array KB contains absorption coefs at the 16 chosen g-values
83!     for a range of pressure levels < ~100mb and temperatures. The first
84!     index in the array, JT, which runs from 1 to 5, corresponds to
85!     different temperatures.  More specifically, JT = 3 means that the
86!     data are for the reference temperature TREF for this pressure
87!     level, JT = 2 refers to the temperature TREF-15, JT = 1 is for
88!     TREF-30, JT = 4 is for TREF+15, and JT = 5 is for TREF+30. 
89!     The second index, JP, runs from 13 to 59 and refers to the JPth
90!     reference pressure level (see taumol.f for the value of these
91!     pressure levels in mb).  The third index, IG, goes from 1 to 16,
92!     and tells us which g-interval the absorption coefficients are for.
