Appendix A: The S and F1N filaments in detail

Figure A.1 shows a zoom on the S and F1N filaments. Several compact, more or less elongated cores are seen in the 250 μm and column density map. The marked dense core N23 has an estimated mass of 13 M.

Detailed view of filament S (panels a)c)) and F1N (df). The 70 and 250 μm units are MJy/sr, column density unit is cm-2. The black cross in panel a) indicates an extended 70 μm source. The blue ellipse in panels d)f) gives the position and extent (FWHM  =  semi-axes) of the dense core N23 of Motte et al. (2007).
