hera_sim.components.SimulationComponent

class hera_sim.components.SimulationComponent(**kwargs)

Base class for defining simulation component models.

This class serves two main purposes:

• Provide a simple interface for discovering simulation component models (see list_discoverable_components()).

• Ensure that each subclass can create abstract methods.

The component(): class decorator provides a simple way of accomplishing the above, while also providing some useful extra features.

Variables:

• is_multiplicative (bool) – Specifies whether the model cls is a multiplicative effect. This parameter lets the Simulator class determine how to apply the effect simulated by cls. Default setting is False (i.e. the model is assumed to be additive unless specified otherwise).

• return_type (str | None) – Whether the returned result is per-antenna, per-baseline, or the full data array. This tells the Simulator how it should handle the returned result.

• attrs_to_pull (dict) – Dictionary mapping parameter names to Simulator attributes to be retrieved when setting up for simulation.

Methods

__call__(**kwargs)	Compute the component model.
get_aliases()	Get all the aliases by which this model can be identified.
get_model(mdl)	Get a model with a particular name (including aliases).
get_models([with_aliases])	Get a dictionary of models associated with this component.

Attributes

attrs_to_pull	Mapping between parameter names and Simulator attributes
is_multiplicative	Whether this systematic multiplies existing visibilities
is_randomized	Whether this systematic contains a randomized component
return_type	Whether the returned value is per-antenna, per-baseline, or the full array
