a) Full G11 filament seen at 70 μm with Herschel/PACS with SPIRE 350 μm contours over-plotted from 9 Jy beam^-1 increasing in steps of 3 Jy beam^-1 (adapted from Henning et al. 2010). The SPIRE 350 μm beam (FWHM) is shown in the lower-left corner. The white rectangle marks the area shown in the rest of the panels. b) MIPS 24 μm image with 3.2 mm continuum contours from a PdBI-only map. The contour levels are from 0.2 to 0.12 mJy beam^-1 in steps of 0.2 mJy beam^-1. The synthesised beam is shown in the lower-left corner. c) APEX-SABOCA 350 μm continuum contours (Ragan et al. 2013) at 0.81, 1.08, 1.35 Jy beam^-1 plotted over the PACS 100 μm image. The SABOCA 350 μm beam (FWHM) is shown in the lower left. d) Integrated intensity of N₂H⁺ (1−0) from the PdBI-only map. e) Integrated intensity of the combined PdBI+MOPRA map. Both d) and e) are integrated from 29 to 33 km s^-1, and the units of the colourscale are Jy beam^-1km s^-1. The + signs indicate the positions of the main continuum cores identified in panel b) and Table 1.
