vis_to_image

xrayvision.imaging.vis_to_image(vis, shape=<Quantity [65., 65.] pix>, pixel_size=<Quantity 2. arcsec>, natural=True)

Create an image by ‘back projecting’ the given visibilities onto the sky.

Parameters:

• vis (xrayvision.visibility.Visibility) – Input visibilities

• shape (Quantity) – Shape of the image, if only one value is given assume square (repeating the value).

• pixel_size (Quantity) – Size of pixels, if only one value is given assume square pixels (repeating the value).

• natural (boolean optional) – Weight scheme use natural by default, uniform if False

Returns:

Quantity – Back projection image
