Table 3:

Estimated diameter of the envelope, position of the secondary source, and respective fluxes, relative to the total flux.
  AMBER (model fitting) AMBER (image reconstruction) MIDI (2006)
Wavelength ( $\mu $m) 1.55 2.45 H-band K-band 8.1 10.5 12.9
  Point + Gaussian + Background Image Point + Gaussian + Background
Envelope size (mas) $3.1 \pm 0.1$ $4.5 \pm 0.1$ - - $\leq$6.5 $\leq$10.6 $\leq$3.5
Envelope flux (% total flux) $61 \pm 2$ $72\pm2$ $\approx$46 $\approx$59 $17 \pm 2$ $9 \pm 1$ $ 6.3 \pm 0.5$
Background flux (% total flux) $12\pm2$ $9\pm2$ $\approx$44 $\approx$25 $69 \pm 13$ $77 \pm 9$ $75 \pm 9$
Secondary flux (% total flux) $27\pm1$ $19\pm1$ $\approx$10 $\approx$16 $14\pm3$ $15\pm2$ $19\pm2$
Secondary separation (mas) $33.48\pm0.03$ $34.5\pm0.5$ $34.6\pm0.5$ $36.8\pm0.1$
Secondary PA ($^{\circ }$) $-4.50\pm0.03$ $-2.5\pm0.8$ $-4.1\pm0.8$ $-26.1\pm1.7$

The envelope flux includes both the southern component and its compact circumstellar envelope fluxes. The errors given for the model-fitting reflects only formal estimates from the $\chi^2$ value.
