In any case, the image row containing the star in each WIC image is shown below, with accompanying estimates of tangent altitudes.
It is pretty clear that the peak emission is below the region where one expects a peak in LBH. The LBH peak in the first plot is around 150-160 km, where the secondary lower peak is right around 90 km. In the second plot it is at 80 km, but the error of this work is at least +- 10 km.
Anyway, from this work one can say a few things.
1) WIC sees terrestrial light from below 100 km. I am a believer now.
2) It is still surprising how sharp the boundary of the bright layer in WIC is. Possibly by coincidence, it maps to the region where diffusive separation of atmospheric constitudents begins, and the number density of the atmosphere drops at a slightly more rapid rate. This, combined with a possible rapid fall-off in NO emissions, might help explain things.
2) By luck or design, but it is quite fortunate that there is no signature of clouds in the images. Anything longward of 220.0 nm would probably show some indication of real weather.
3) The moon makes itself useful every 28 days. It has a strong signature of hot HI due to scattering of solar light.
5) It's not shown very well in these 3 pages, but the 1356 peak matches up nicely with what looks to be the LBH emission in WIC (the fainter second layer).
