Governing equation: Flux = ∫Intensity * cos(q) dΩ

In spherical coordinates:
Flux =
Solving the integral using m= cos(q) gives us:
Flux = Intensity * Ω
To go from the spectrum from VisRad
to a boosted up spectrum:
Flux (Dante at the LEH) = Flux (Dante from VisRad)*
p
/Solid Angle of the LEH
So our correction factor to convert the Dante
spectrum from VisRad to the Dante spectrum at the LEH is
p/(Solid
Angle of the LEH) = 1.962 x 106 (in
our simulation, the
DANTE surface is at 100 cm)
Converting the VisRad DANTE spectrum to the DANTE spectrum
