Results from the geometric modeling of the VEGA V2 data in the close-by continuum band (635–650 nm) and in the band centered on Hα (649–664 nm).

Continuum (635–650 nm) Hα (649–664 nm)


Model θ1 (mas) θ2 (mas) F2 θ1 (mas) θ2 (mas) F2
1 UD 0.28 ± 0.01 1.1 0.36 ± 0.01 2.8
2 UDs 0.27 ± 0.02 0.03 ± 0.03 1.1 0.26 ± 0.02 6.5 ± 2.1 0.15 ± 0.03 1.3

Notes. For each band, many models were tested, but only these composed of one and two uniforms disks (UD) are presented here. The angular diameter of each UD component is denoted as θ1 and θ2. The normalized flux contribution of the first and second model components are, respectively, F1 and F2 (F1 + F2 = 1). All parameters were free in our modeling.
