Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

! PURPOSE OF THIS SUBROUTINE:
! Interpolates the beam transmittance vs. cosine angle table.
! METHODOLOGY EMPLOYED: na
! REFERENCES: na
! USE STATEMENTS:
USE FluidProperties, ONLY: FindArrayIndex ! USEd code could be copied here to eliminate dependence on FluidProperties
IMPLICIT NONE ! Enforce explicit typing of all variables in this routine
! FUNCTION ARGUMENT DEFINITIONS:
REAL(r64), INTENT(IN) :: COSI ! Cosine of the incident angle
REAL(r64), DIMENSION(NumOfAngles), INTENT(IN) :: transBeam ! Table of beam transmittance vs. cosine angle
! FUNCTION LOCAL VARIABLE DECLARATIONS:
INTEGER :: Lo, Hi
REAL(r64) :: m, b
! FLOW:
InterpolatePipeTransBeam = 0.0d0
! Linearly interpolate transBeam/COSAngle table to get value at current cosine of the angle
Lo = FindArrayIndex(COSI, COSAngle)
Hi = Lo + 1
IF (Lo > 0 .AND. Hi <= NumOfAngles) THEN
m = (transBeam(Hi) - transBeam(Lo)) / (COSAngle(Hi) - COSAngle(Lo))
b = transBeam(Lo) - m * COSAngle(Lo)
InterpolatePipeTransBeam = m * COSI + b
ELSE
InterpolatePipeTransBeam = 0.0d0
