【 摘 要 】

The observations of astrophysical sources in a large frequency range (from radio to very high energy gamma-ray bands) provide complete information on the nonthermal processes taking place in different objects. The modeling of acquired data is crucial for understanding the particle acceleration and emission processes. In this paper a new code that can derive the model free parameters that statistically best describe the observed data is presented. It derives the best-fit parameters and their uncertainties through Markov Chain Monte Carlo sampling of the likelihood distributions. Various processes for the cooling of electrons are included in the code which allows its wide application. The code is applied to model the broadband spectral energy distributions of two well-known blazars – Mkn 501 and PKS 0537-441. Using the obtained parameters, the physical processes in their relativistic jets are discussed.
