Top: core-to-lobe radio flux density ratio vs. FWHM(Hβ), adapted from Wills & Browne (1986). Colored dots represent sources of our sample: red dots represent A1 RL FRII sources, yellow dots B1 RL FRII, green B1⁺ RL FRII and blue ones B1⁺⁺ RL FRII. Black dots are the original data from Wills & Browne (1986). The magenta line represents the change of R with FWHM(β), predicted by the Orr & Browne (1982) beaming model with R_T = 0.024 and γ = 5. Bottom: FWHM(β) vs. inclination, derived from R_c through Eq. (16).
