Best runs for f_γcut = uniform (top panels), f_γcut = log-uniform (middle panels), and f_γcut = linear (bottom panels). The left panels show the Π_opt-versus-ν_p^S limiting envelopes for both the MC simulations and the observed RoboPol data, the center panels show the trends of the MC-averaged dispersion of the MC optical EVPA angle vs ν_p^S, and in the right panels, the IXPE HPS observed trends compared to the MC results extracted from the same runs used for the RoboPol panels.
