Various configurations of our GG Tau A model to investigate influence of each individual circumstellar disk around stars Aa, Ab1, and Ab2 on the emission of circumbinary disk.

#	Configuration	Aa	Ab1	Ab2
1	No circumstellar disks	–	–	–
2	Disk around Aa	✓	–	–
3	Disk around Ab1	–	✓	–
4	Disk around Ab2	–	–	✓
5	Disks around Aa and Ab1	✓	✓	–
6	Disks around Aa and Ab2	✓	–	✓
7	Disks around Ab1 and Ab2	–	✓	✓
8	Disks around all stars	✓	✓	✓

9	Vertical disk around Ab2	✓	✓	✓ⁱ

Notes. Each star is either surrounded by its circumstellar disk (✓) or has no surrounding dust (–). The CS disk with ✓ⁱ has an inclination of i = 90° with respect to the plane of the CB disk and a position angle of the rotation axis of 270°.
