note that in all these cases, the colors are very clearly clustered. but the overall distribution still is in a sort of balloon.
and for 20120525, it has the same nub, but then from another view, two lobes:
and then the two 2013 days just have way less data:
"You could treat your data as a sample from a three-dimensional probability density, and estimate that density on a grid, e.g. via a 3d histogram, or better a 3d kernel density estimator. Then apply a threshold and extract the surface using isosurface."
no isosurface, but i've evaluated by p-hat density estimation and found points where the p-hat is in the 75-76th percentile
the black dots are data, and the red dots are the boundary defined by where p-hat is in the 90-91st percentile
here's observed on the left, and cloud-hab on the right. note how cloud-hab doesn't fill the same space at all--it's less spread out. but at least it's not outside of it!
and it turns out that left clump are the kinematics the cloud does poorly at:
(green are the 180+ directions)
so this realization has led to two things:
i mean, check it out: it's got clear BOUNDARIES
