Spatial distribution of sources with thick disks a) and anaemic disks b). Embedded sources (A_V > 3 mag) are represented by filled circles, and unembedded sources (A_V ≤ 3 mag) are represented by open circles. The spatial extent of the molecular cloud is represented by a grey contour of A_V = 8 mag. Both maps are centred on IRS 2. For positional reference, the sources IRS 1, IRS 2, and S Mon are represented by plus signs, while the approximate southeastern edge of the Fox Fur Nebula is marked by a dashed curve in panel b).
