convolve_models_fft

astropy.convolution.convolve_models_fft(model, kernel, bounding_box, resolution, cache=True, **kwargs)

Convolve two models using convolve_fft.

Parameters:

modelModel

Functional model

kernelModel

Convolution kernel

bounding_boxpython:tuple

The bounding box which encompasses enough of the support of both the model and kernel so that an accurate convolution can be computed.

resolutionpython:float

The resolution that one wishes to approximate the convolution integral at.

cacheoptional, bool

Default value True. Allow for the storage of the convolution computation for later reuse.

**kwargspython:dict

Keyword arguments to be passed either to convolve or convolve_fft depending on mode.

Returns:

defaultCompoundModel

Convolved model
