A family of spectral decompositions of the spin-weighted spheroidal waveoperator is constructed for complex aspherical parameters with boundedimaginary part. As the operator is not symmetric, its spectrum is complex andJordan chains may appear. We prove uniform upper bounds for the length of theJordan chains and the norms of the idempotent operators mapping onto theinvariant subspaces. The completeness of the spectral decomposition is proven.
