Astropy spline. A number of predefined 1-D and 2-D models are provided and the capability for custom, user defined models is supported. The Astropy community is committed to supporting the community code of conduct. Please remember to acknowledge and cite the use of Astropy! Feb 3, 2026 · specutils is a Python package for representing, loading, manipulating, and analyzing astronomical spectroscopic data. The generic data containers and accompanying modules provide a toolbox that the astronomical community can use to build more domain-specific packages. x array_like The x data values.
