Radially averaged Lorentz factor as a function of distance for all the simulated models. Top panel: magnetically dominated jet models. Bottom panel: thermally and kinetically dominated jet models. The different data points are the Lorentz factor for different epochs and frequencies of NGC 315 inferred by Ricci et al. (2022). The continuous lines represent the force-free magnetically dominated models, the dashed lines the force-free thermally dominated ones, the dotted lines are for the kinetically dominated model, and the dashed-dotted lines for the nonforce-free configurations.
