predict_visibility

ska_sdp_func_python.imaging.imaging.predict_visibility(vis: Visibility, model: Image, context='ng', gcfcf=None, **kwargs) → Visibility[source]

Predict Visibility from an Image.

For awprojection, the gridding details must be supplied via a tuple of (gridding correction function, convolution function) or a partial to calculate it.

Parameters:

  • vis – Visibility to be predicted

  • model – model Image

  • context – Type: 2d or awprojection, ng or wg (nifty-gridder or WAGG GPU-based gridder/degridder), default: ng

  • gcfcf – Tuple of (grid correction function, convolution function) or partial function

Returns:

Resulting Visibility (in place works)
