- Parameters:
vis (
xrayvision.visibility.Visibility
) – Input visibilitiesshape (
astropy.units.quantity.Quantity
, optional) – Shape of the image, if only one value is given assume square (repeating the value).pixel_size (
Tuple[~astropy.units.Quantity]
, 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 ifFalse
