The Relationship Between the FR-I Type and the FR-II
The radio-optical-X-ray spectral properties of the FR-I and the FR-n type radio sources are compared in this paper. The FR-I radio sources have much flatter radio-optical spectra (△αro≈0.19),but much steeper optical-X-ray and radio-X-ray spectra (△αox≈0.40; △αrx≈0.10). There is a marginal evidence that FR-II (G) might be the intermediate state from FR-II (Q) to FR-I radio sources.
