Pluto and Charon limb profile topography

We derived updated and expanded topography datasets for Pluto and Charon.
This is done through finding the body edge (i.e. the limb) in images, and
with those body edge locations we can apply simple geographical techniques
to produce limb profiles. The process involves some human intervention,
but is primarily automation based. Our limb profile topography is useful
for geologic and geophysical studies of Pluto and Charon. Additionally, we
provide processed data of how we used the limb profile data in our study.
The first set of additional data is the result of the processing required
to determine the Fourier transformation that breaks down the data into its
wavelength based components. This is done by interpolating the raw data
onto a evenly spaced grid, then detrending the data by setting the
end-points to equal elevations. Our second addition has the base 10
logarithm of our variance spectra results for Pluto and Charon, which is
the primary result of the scientific portion of the study. We found that
Charon has a statistically significant break in slope, while Pluto does
not. This is likely a signal of their crust's structures.
