Why & how

SpectralFitting.jl is a package for fitting models to spectral data, similar to XSPEC, Sherpa or ISIS.

The rationale for this package is to provide a unanimous interface for different model libraries, and to leverage advancements in the computional methods that are available in Julia, including the rich statistics ecosystem, with automatic-differentiation and speed.

Longer term ambitions include

• Multi-wavelength fits
• Radiative transfer embedded into the package
• Spectral and timing fits

SpectralFitting aims to provide highly optimised and flexible fitting algorithms, along with a library of spectral models, for use in any field of Astronomy that concerns itself with spectral data.
