Model SEDs of a star surrounded by rotationally flattened envelope for different inclinations in the range (0°,90°) with an increment of 30°, see the key for different linestyles representing different inclinations. The points with error bars correspond to observationally inferred values, see Table 2. Left panel: maximum radius of the envelope is set to r_max = 0.5 AU. Middle panel: r_max = 5 AU. Right panel: r_max = 50 AU.
