vis_to_map#
- xrayvision.imaging.vis_to_map(vis, shape=<Quantity [65., 65.] pix>, pixel_size=<Quantity 1. arcsec / pix>, scheme='natural')[source]#
Create a map by performing a back projection of inverse transform on the visibilities.
- Parameters:
vis (Visibilities) – Input visibilities
shape (Quantity) – Shape of the image, if only one value is passed, assume square (repeating the value).
pixel_size (Quantity | None) – Size of pixels, if only one value is passed, assume square pixels (repeating the value).
scheme (str | None) – Weight scheme natural by default.
- Returns:
Map object with the map created from the visibilities and the metadata will contain the offset and the pixel size
- Return type:
