The specutils package provides a basic interface for the loading, manipulation, and low-level analysis of spectroscopic data. The intention is for the generic data containers and accompanying modules to provide a basis for the astronomical community upon which more robust tooling can be built.

The basic data container of specutils is the :class:~`specutils.spectra.Spectrum1D` class. It contains logic to handle multi-dimensional flux data, spectral axis in various forms (wavelenth, frequency, energy, velocity, etc.), convenient and unobtrusive wcs support, and uncertainty handling. This core container also maintaines a few other features including unit support, custom data loading, arithmetic operation support, and multi-dimensional flux data support.

Note

support for collections of spectra with distinct spectral axes information is slotted for a future release.
