Model gallery

In general the models are grouped into the following categories:

• SpectralModel: models to describe spectral shapes of sources

• SpatialModel: models to describe spatial shapes (morphologies) of sources

• TemporalModel: models to describe temporal flux evolution of sources, such as light and phase curves

• SkyModel and SkyDiffuseCube: model to combine the spectral and spatial model components

The models follow a naming scheme which contains the category as a suffix to the class name.

The model gallery provides a visual overview of the available models in Gammapy.
