Create a map of the point spread function for given the visibilities.
- Parameters:
vis (Visibilities) – Input visibilities
shape (Annotated[Quantity, Unit("pix")]) – Shape of the image, if only one value is passed, assume square (repeating the value).
pixel_size (Annotated[Quantity, Unit("arcsec / pix")] | None) – Size of pixels, if only one value is passed, assume square pixels (repeating the value).
scheme (str | None) – Weight scheme to use natural by default.
- Returns:
Map of the point spread function
- Return type:
