Surface brightness, position angle, and ellipticity profiles for three photometric models described in this Appendix B.2, at different inclinations θ (θ = 0 for face-on, θ = 90 edge-on). For each photometric model, we show one random projection in each of six intervals Δθ = 15 degrees, starting from near face-on (Δθ = 0−15 degrees, darkest color profile), through Δθ = 15–30 degrees, etc., to near edge-on (Δθ = 75–90 degrees, lightest profile). These Δθ intervals represent 3%, 10%, 20%, 19%, 21%, 27% of 100 random directions, from face-on (darkest) to edge-on (lightest profiles).
