Column density map of the Musca filament from the HGBS (André et al. 2010; Cox et al. 2016) embedded in the large scale 2MASS extinction map of Musca, scaled to the Herschel column density, that traces the ambient cloud. The extinction map was produced by the A_V mapping tool in Schneider et al. (2011). The black boxes indicate the maps made with the APEX telescope, the red box indicates the area displayed in Fig. 4, and the blue box indicates the area mapped with the NANTEN2 telescope. The black triangles show the locations of the stars with a distance smaller than 140 pc and a significant reddening (> 0.3) in the Gaia catalogue. The blue triangle shows the location of the only young stellar object (YSO) in the Musca filament.
