Hierarchical fragmentation of the G205.46-14.56 filament. (a) Herschel 500 μm continuum emission. Contours are shown from 10% to 90% in steps of 10% of the peak flux intensity (22.3 Jy beam⁻¹). (b) JCMT 850 μm continuum emission. Contours are [0.05, 0.1, 0.2, 0.4, 0.6, 0.8] times the peak flux intensity (2.53 Jy beam⁻¹). (c) 1.3 mm continuum emission from ACA 7-m array observations is shown in contours overlaid on Spitzer 4.5 μm emission. Contours are [0.2, 0.4, 0.6, 0.8]  ×  86.4 mJy beam⁻¹. (d) Contours show 1.3 mm continuum emission from combined ACA and ALMA data with an angular resolution of ∼1″. Contour levels are [0.1, 0.3, 0.5, 0.7, 0.9]  ×  42.7 mJy beam⁻¹. The background image shows 1.3 mm continuum emission from the combined ACA and ALMA data with an angular resolution of ﹩\sim 0\mathop{.}\limits{^{\prime\prime} }35﹩.
