synthesizer.emission_models.operations

A submodule containing the operations performed by an EmissionModel.

An emission models inherits each of there opertaion classes but will only ever instantiate one. This is because operations are isolated to one per model. The correct operation is instantiated in EmissionMode._init_operations.

These classes should not be used directly.
