The index of the subdomain on which the operator should act
If None, it is set to 0 if `domain` contains exactly one space.
`domain[space]` must be of type `RGSpace`, `HPSpace`, or `GLSpace`.
Notes
-----
The operator assumes periodic boundaries in the input domain. This means for a sufficiently
broad function a point source close to the boundary will blur into the opposite side of the
image. Zero padding can be applied to avoid this behaviour.
