Beaming models and the correlations between the core dominance parameter   and the core and extended powers of quasars
  We investigate the recent claim by Qin et al. that the observed correlations (or lack thereof) between the core dominance parameter and the core and extended powers of samples of lobe- and core-dominated quasars is in contradiction with beaming models. Contrary to their conclusion, we find that their results are in perfect agreement with such models, and support this assertion with Monte Carlo simulations.
