vis_to_image#
- xrayvision.imaging.vis_to_image(vis, shape=<Quantity [65., 65.] pix>, pixel_size=<Quantity 1. arcsec / pix>, scheme='natural')[source]#
Create an image by ‘back projecting’ the given visibilities onto the sky.
- 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) – Weight scheme natural by default.
- Returns:
Back projection image
- Return type:
