The emission from blazar jets is strongly variable and non-thermal. Its spectral energy distribution (SED) is characterized by two humps located, respectively, at IR‐X-ray and MeV-TeV frequencies. By modelling and fitting observational blazar SEDs we can derive the physical properties of these sources and better understand the processes that occur at very high energies. Even though several models have been proposed to describe blazar emission, so far SED models have been obtained only (mostly) heuristically. In this article we present a statistically rigorous approach and its implementation to efficiently rule out models for specific sources ‐ when simultaneous datasets are available. We will also digress on some still unsolved technical problems that may appear when dealing with multi-frequency datasets, an dr eport on recent progress to solve them.Read More
