ALMA band 6 (1.3 mm) continuum image of G17.64 made with a robust 0.5 value. The contour levels are set at −3, 5, 10, 50 and 200 σ (1 σ = 0.07 mJy beam⁻¹) to indicate the weak southern sources and the strength of G17.64 (negative contours are dashed lines). The map is centred (0,0) on G17.64 at J2000 18^h 22^m26.385^s −13°30′11.97″. The synthesised beam is indicated to the bottom left of the figure, while a scale bar is shown in the bottom right.
