create_image_from_visibility

ska_sdp_func_python.imaging.base.create_image_from_visibility(vis: Visibility, **kwargs) → Image[source]

Make an empty Image from params and Visibility.

This makes an empty, template Image consistent with the Visibility, allowing optional overriding of select parameters. This is a convenience function and does not transform the visibilities.

Parameters:: vis – Visibility

Optional kwargs: :param phasecentre: Phasecentre (Skycoord) :param channel_bandwidth: Channel width (Hz) :param cellsize: Cellsize (radians) :param npixel: Number of pixels on each axis (512) :param frame: Coordinate frame for WCS (ICRS) :param equinox: Equinox for WCS (2000.0) :param nchan: Number of image channels (Default is 1 -> MFS) :return: Image
