shift_vis_to_image

ska_sdp_func_python.imaging.base.shift_vis_to_image(vis: Visibility, im: Image, tangent: bool = True, inverse: bool = False) → Visibility[source]

Shift visibility in place to the phase centre of the Image.

Parameters:

  • vis – Visibility

  • im – Image model used to determine phase centre

  • tangent – Is the shift purely on the tangent plane True|False

  • inverse – Do the inverse operation True|False

Returns:

Visibility with phase shift applied and phasecentre updated
