Observations at gamma-ray and radio frequencies suggest that the parsec-scale environment of the launch sites of relativistic jets from AGN leaves imprints on the Doppler-beamed emission from the jets. We use these trends to test the hypothesis that the blazar divide constitutes a dichotomy. Obtaining a handle on the Doppler factor can play a key role in building a consistent picture of the jets and their relationship with the central supermassive black hole accretion system, especially in the framework of unification schemes. We will present some work in progress from such an investigation. |
