By manipulating the Elevation Min and taking screenshots and counting pixels, a calibration curve can be developed for the cameras. This is necessary if an accurate sextant is to be developed.
Notice that both curves are the same shape, but differ slightly in the magnitude of the correction. This seems to be a feature of how the rendering engine displays external views in SH3. Very interesting...It makes you wonder if a similar distortion exists in the horizontal direction for bearings.
That is all for today. Next up will be the actual sextants and measuring the position of some navigation stars.
Good hunting.
<Edit> Reposted calibration curves after correcting a math error. Sorry.
