We present the details of a recent statistical study in which parameters for Active Galactic Nuclei one zone Synchrotron-Self Compton (SSC) models have been determined by statistically rigorous fits of simultaneous multiwavelength datasets. Guided by this example we will see how, improving over common eye-ball fits, results obtained with a full-fledged chi squared minimization procedure already suggest that existing observations might require improvements to some one-zone SSC models.
