mufasa.UltraCube

The mufasa.UltraCube module provides tools for processing, analyzing, and visualizing spectral cubes, particularly for fitting multi-component spectral models.

Classes

UCubePlus	A subclass of UltraCube that includes directory management for parameter maps and model fits.
UltraCube	A framework for multi-component spectral cube analysis and model fitting.
