(a) Illustrative dipole orientation with azimuthal angle ϕ and inclination angle θ. The optical axis is assumed to be parallel to the z-axis. PSF intensity patterns with no astigmatism (b,d) and 75 nm RMS vertical astigmatism (c,e). The inclination angle is set to θ = π/2, π/3, π/6, 0 and the azimuthal angle is ϕ = 0 (b,c) and ϕ = π/4 (d,e). The black cross indicates the actual position of the dipole emitter.
