vis_to_map#

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

Create a map by performing a back projection of inverse transform on the visibilities.

Parameters:

vis (xrayvision.visibility.Visibility) – Input visibilities
shape (int (m, n)) – Shape of the image, if only one value is given assume square (repeating the value).
pixel_size (float (dx, dy), optional) – 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:

sunpy.map.Map – Map object with the map created from the visibilities and the metadata will contain the offset and the pixel size
