Python version of the MATLAB code in this Stack Overflow post: https://stackoverflow.com/a/18648210/97160

The example shows how to determine the best-fit plane/surface (1st or higher order polynomial) over a set of three-dimensional points.

Implemented in Python + NumPy + SciPy + matplotlib.

This re-styles your sublime text sidebar to be dark, it fits default Monokai theme.

Save the Default.sublime-theme file into packages/Theme - Default, make a backup of your original if you want to be able to go back easily.

"""
Match two sets of on-sky coordinates to each other.
I.e., find nearest neighbor of one that's in the other.

Similar in purpose to IDL's spherematch, but totally different implementation.

Requires numpy and scipy.
