Muon baffle-crossing conditions (Equation (38) and (39)) shown for muons with different normalized impact distances ρ_R and impact angles ϕ₀, for the parameters of an SCT. In the left panel, the muon is inclined toward the left (ψ = 0°) with varying inclination angles ν, in the central panel, it is inclined toward the right (ψ = 180°), and in the right panel the inclination angle is fixed at ν = 4°, while the azimuthal projection ψ varies. Note that the azimuthal axis represents here the muon angle ϕ₀, whereas in the previous figures the photon emission angle ϕ − ϕ₀ was used. The gray shaded region in the center indicates the central hole in the primary mirror.
