Table 5:

$\chi ^2_{\rm red}$ values obtained comparing the visibility amplitudes observed and modeled at 1.3 mm.
$\lambda = 1.3$ mm	Model centered	Model centered	Model centered
	in between A and B	on B	on A
Model	$\chi ^2_{\rm red}$	$\chi ^2_{\rm red}$	$\chi ^2_{\rm red}$
Single power-law	18.5	10.2	8.5
Shu-like	13.3	10.3	8.3
Central cavity	11.0	11.3	9.9

Notes. The number of degrees of freedom $\nu$ is 10230. The 1st column reports the $\chi ^2_{\rm red}$ obtained using the synthetic maps with the envelope centered on the mid-way point between the sources A and B. The 2nd and the 3rd columns report the $\chi ^2_{\rm red}$ obtained using the synthetic maps with the envelope centered on the source B and on the source A, respectively. The 1st, the 2nd, and the 3rd lines report the $\chi ^2_{\rm red}$ obtained in all the cases discussed in the text, using the model of envelope with a single power-law density distribution, a Shu-like density distribution, and a central cavity of Schöier et al. (2004), respectively.
