Abstract:
    We complied the optical, X-ray, and γ-ray data for 54 Fermi
    blazars and studied the relationship between the broadband spectral
    index αox and αxγ, as well as the relationship
    between the intrinsic composite spectral indices αxox and
    αγxγ for this sample. The relationship between
    αxox and αγxγ reveals that flat spectrum
    radio quasars and low-energy peaked BL Lacertae follow a continuous
    trend, which is consistent with previous results, whereas high-energy
    peaked BL Lacertae follow a separate distinct trend. Even so, a
    unified scheme is also revealed from
    αxox-αγxγ diagram when all three
    subclasses of blazars are considered.
