vis_psf_image

xrayvision.imaging.vis_psf_image(vis, *, shape=<Quantity [65., 65.] pix>, pixel_size=<Quantity 1. arcsec / pix>, scheme='natural')

Create the point spread function for given u, v point of the visibilities.

Parameters:

• vis (Visibilities) – Input visibilities

• shape (Annotated[Quantity, Unit("pix")]) – Shape of the image, if only one value passed, assume square (repeating the value).

• pixel_size (Annotated[Quantity, Unit("arcsec / pix")]) – Size of pixels, if only one value is passed, assume square pixels (repeating the value).

• scheme (str) – Weight scheme, natural by default.

Returns:

Point spread function

Return type:

Quantity
