Appendix A: Dust extinction maps and CO data.
 |
Fig. A.1
IRDC complex 36.74-00.16. The panels show the NIR dust extinction, 13CO line emission, 8 μm dust opacity, and 870 μm dust emission maps of the complex. The contours of the AV map start from 3 mag and the step is 4 mag. The contours of the CO map are in multiples of 15 K km s-1. The velocity range chosen for 13CO data is shown in the CO map. The 8 μm color scale saturates white at AV ≈ 20 mag and the color scale of the 870 μm map at AV ≈ 7 mag. The panels show a scale bar corresponding to the distance derived using foreground source count method (Dfg in Table 1). |
