eddy - Extracting Disk Dynamics

eddy provides a suite of tools to extract kinematical information from spatially and spectrally resolved line data.

The eddy.rotationmap.rotationmap class enables the fitting of a Keplerian rotation pattern to a rotation map to infer geometrical properties of the disk, a dynamical mass of the star, or to infer the presence of a flared emission surface or warp in the disk.


Installation is as easy as,

pip install astro-eddy

If you want to live on the edge, you can clone the repository and install that,

pip install .

but I cannot promise everything will work as described here.
