37	! Set arrays needed for the g-point reduction from 224 to 112 for the
38	! 14 SW bands:
39	! This mapping from 224 to 112 points has been carefully selected to
40	! minimize the effect on the resulting fluxes and cooling rates, and
41	! caution should be used if the mapping is modified.
42	!
43	! JPGPT The total number of new g-points (NGPT)
44	! NGC The number of new g-points in each band
45	! NGS The cumulative sum of new g-points for each band
46	! NGM The index of each new g-point relative to the original
47	! 16 g-points for each band.
48	! NGN The number of original g-points that are combined to make
49	! each new g-point in each band.
50	! NGB The band index for each new g-point.
51	! WT RRTM weights for 16 g-points.
52	! Use this NGC, NGS, NGM, and NGN for reduced (112) g-point set
53	! (A related code change is required in modules parsrtm.F90 and yoesrtwn.F90)
