This is a list of models we plan to put into the astropy core before the 0.3 release. Discussion: https://github.com/astropy/astropy/issues/981

Here's the list of models already in astropy.modeling.models: http://docs.astropy.org/en/latest/models/index.html

These lists were generated by going through these lists and selecting the models that seem general and often-used enough to be in astropy core:

• http://cxc.cfa.harvard.edu/sherpa/models/
• http://pythonhosted.org/Astropysics/coremods/models.html
• http://pythonhosted.org/PyModelFit/builtins.html#classes
• Gammalib spatial and spectral

• beta1d and beta2d
• box1d and box2d
• delta1d and delta2d
• disk2d: constant within some radius.
• king2d
• lorentz1d and lorentz2d
• voigt - this can be implemented as the convolution of lorentz1d and gauss1d
• poisson
• schechter
• shell2d
• sersic2d
• Gauss-hermite series e.g. in astropysics - some of the stuff in numpy.polynomial.hermite may be helpful here
• Power law. In Sherpa and GammaLib - see PR #1184, this will probably be in soon
• Exponential cutoff power law. In GammaLib
• Broken power law. In sherpa and PyModelFit
• Curved power law. In sherpa and GammaLib

• Blackbody. In Sherpa: blackbody and bbody and bbodyfreq
• bremsstrahlung

• Navarro, Frenk, and White 1996 profile – the canonical dark matter halo profile; in Astropysics
• Generic alpha-beta-gamma models common in mass modeling (NFW is a subset of this) in PyModelFit
• Plummer sphere (Plummer 1911) in Astropysics
• King2D
• King3D - this is the deprojected version of king2d

• Table models (see tablemodel in Sherpa or LinearInterpolatedModel or NearestInterpolatedModel in PymodelFit 1D and 2D table models in GammaLib) with a few interpolation options. This is very important but I think should be discussed in a separate issue, with the discussion here focusing on "analytical" or "functional" or "mathematical" models.

To avoid duplication of effort if you intend to work on implementing a new model please create an issue on github stating so.

• delta1d and delta2d

• king2d

• lorentz2d

• poisson

• Curved power law. In sherpa and GammaLib

• bremsstrahlung
