\tablefoot{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 \citet{Sch04}, respectively.}
