Top panel: radio-loudness as a function of the orientation angle for the simulated NLS1 sample. Middle panel: orientation angle distribution for simulated radio-detected NLS1s. Our simulated samples have average orientations of (RL-NLS1) and (RQ-NLS1), and we can infer θ_RL-NLS1 ~ 9°. Bottom panel: radio flux density distributions for simulated and real samples. Red and blue symbols and lines in all panels refer to simulated RL- and RQ-NLS1s, while black and green lines in the bottom panel refers to the observed RL and RQ populations present in Järvelä et al. (2015).
