The deproject.deproject module

Deproject 2-d circular annular spectra to 3-d object properties.

This module implements the “onion-skin” approach popular in X-ray analysis of galaxy clusters and groups to estimate the three-dimensional temperature, metallicity, and density distributions of an optically-thin plasma from the observed (projected) two-dimensional data, arranged in concentric circular annuli.
