Identification of sources discussed in the text, in the vicinity of G010.32−00.15. a) Column density map showing the five clumps present at the waist of the bipolar nebula (red contour levels at 0.3, 0.5, 0.75, 1.0, 1.5, and 2.0 × 10²³ cm^-2). b) Spitzer 5.8 μm image; the plus symbols show the positions of the methanol masers, of the EGOs, the MYSOs, the UC H ii region, and IRAS18060-2005; the exciting star is also identified. The orange arrows show the pressure exerted by the ionized gas trying to escape from the central ionized region through the molecular shell, between the dense clumps. c) MAGPIS image at 21 cm showing the UC H ii region and the dense ionized layers bordering the IF (especially the borders of C2 and C3 turned towards the exciting cluster).
