Snapshot: synchrotron emission map of the different types of jets (H, T, P, and HL) without ejecta and stationnary. Each map represent the flux intensity in mJy unit. The R and Z-axis are given in R_jet unit. These maps represent a resolution of the radiative transfer equation with an angle between the jet propagation axis and the line of sight equal to θ_obs = 90° and ν = 1 GHz.
