predict_awprojection

ska_sdp_func_python.imaging.base.predict_awprojection(vis: Visibility, model: Image, gcfcf=None) → Visibility[source]

Predict using convolutional degridding and an AW kernel.

Note that the gridding correction function (gcf) and convolution function (cf) can be passed as a partial function. So the caller must supply a partial function to calculate the gcf, cf tuple for an Image model.

Parameters:

  • vis – Visibility to be predicted

  • model – model Image

  • gcfcf – Grid correction function i.e. in image space, Convolution function i.e. in uv space

Returns:

Resulting Visibility (in place works)
