pycows 0.0.1

Cosmic filament finder

The cows python package is an implementation of the cosmic filament finder COsmic Web Skeleton (COWS). The cosmic filament finder works on Hessian-based cosmic web idetifier (such as the V-web) and returns a catalogue of filament spines.

It works by identifying the medial axis, or skeleton, of cosmic web filaments and then separating this skeleton into individual filaments. For more information of the specifics of the method, see here.
