hera_sim.sigchain.WhiteNoiseCrosstalk¶

class hera_sim.sigchain.WhiteNoiseCrosstalk(amplitude=3.0, rng=None)[source]¶

Generate cross-talk that is simply white noise.

Parameters:

amplitude (float, optional) – The amplitude of the white noise spectrum (i.e. its standard deviation).
rng (np.random.Generator, optional) – Random number generator.

Methods

`__call__`(freqs, **kwargs)	Compute the cross-correlations.
`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
