NOTES :

Bold number is extrapolated.
wl : wavelength in namometers (nm).
Spectral Radiance units are nw/cm2/sr/nm. Each picoamp gives this many SRunits.
Integral of SpRad*wind*optics*filt1*filt2*qe over wl weights the SpRad*wind by the bandpasses of the components seeing the light.
Integral of optics*filt1*filt2*qe over wl is the weighting function to divide out.
R=result: the weighted average SpRad/pa that was transmitted through the window.
