Synthetic images of β Lyr A system for five different models: slab power-law, slab steady, wedge power-law, wedge steady, and nebula. The scale of grays corresponds to the monochromatic intensity I_v (in erg s⁻¹ cm⁻² sr⁻¹ Hz⁻¹). The wavelength is always λ = 545 mn and the orbital phase 0.25; α goes along east–west direction, and δ along north–south direction. It is worth noting that each model converged independently, but the outcomes are remarkably similar in terms of geometry.
