We present simulated maps showing the appearance in total intensity of flows computed using a relativistic hydrodynamic code (Duncan k. Hughes 1994: ApJ, 436, L119). The radiation transfer calculations allow for full treatment of relativistic effects, such as Doppler boosting and time delay. Depending on viewing angle, and the speed of emitting features, the appearance of a jet can be strongly influenced by either effect; in both cases the map differs dramatically from the morphology exhibited by the hydrodynamic quantities.
