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`.
- without_mean: bool, optional
- If `None`, chooses domain-dependant default value:
- - `True` for spherical domains (`HPSpace`, `GLSpace`)
- - `False` for RGSpaces.
- If `True`, subtracts the input mean before applying the convolution
- and adds it back afterwards.
