V = 1 → 0 P10 fundamental band CO ro-vibrational line profiles for circular Keplerian (dashed lines) and eccentric disk (solid lines) in the 600th binary orbit. The disk extensions were 0.4−40 AU and 0.2−20 AU for panel left and right, respectively. The line profiles for inclinations i = 60° and i = 20° are shown with blue and red colors, respectively. The magnitude of asymmetry is larger for higher inclination angles. Although the line fluxes normalized to the continuum are clearly different, the magnitude of asymmetry remains the same for model #1 and #2.
