!-* This program calculates the upward fluxes, downward fluxes,
14
!   and heating rates for an arbitrary atmosphere.  The input to
15
!   this program is the atmospheric profile and all Planck function
16
!   information.  First-order "numerical" quadrature is used for the
17
!   angle integration, i.e. only one exponential is computed per layer
18
!   per g-value per band.  Cloud overlap is treated with a generalized
19
!   maximum/random method in which adjacent cloud layers are treated
20
!   with maximum overlap, and non-adjacent cloud groups are treated
21
!   with random overlap.  For adjacent cloud layers, cloud information
22
!   is carried from the previous two layers.
