It's the band thing.
If e = 1 in the band which the camera can "see", and significantly lower
in the rest of the spectrum, then the equations they used will show a
(perhaps markedly) higher power than was actually generated.
Or do I have it backward? Damn! this stuff is confusing.
Anybody out there with a still functioning brain?
I think such a weird e spectrum would very unlikely!

If they take emissivity = 1 then they are assuming the worst value for

range lead to an over estimation of power?
