Appendix A: The 12CO, 13CO and continuum maps
 |
Fig. A.1
The integrated intensities of the 12CO maps of integrated area toward a) MON R2, b) S156, c) DR17/L906, and d) M17/M18. The color-scale maps are the same as Fig. 1. a) For the MON R2 region: 12CO contour levels are from 12.80 to 34.14 in steps of 4.27 K km s-1. b) For the S156 region: 12CO contour levels are from 12.63 to 33.69 in steps of 4.21 K km s-1. c) For the DR17/L906 region: 12CO contour levels are from 12.72 to 39.26 in steps of 4.91 K km s-1. d) For the M17/M18 region: 12CO contour levels are from 29.34 to 78.24 in steps of 9.78 K km s-1. |

Fig. A.2
Position-velocity diagrams of 12CO for a) MON R2, b) S156, c) DR17/L906, and d) M17/M18. The positions for 12CO are the same as Fig. 2. For the MON R2, S156, and M17/M18 regions, contour levels are 3 to 8 in steps of 1 K. Contour levels are 1.3 to 6.3 in steps of 1 K for the DR17/L906 region. |

Fig. A.3
The integrated intensities of the 13CO maps of integrated area toward a) MON R2, b) S156, c) DR17/L906, and d) M17/M18. The color-scale maps are the same as Fig. 1. a) For the MON R2 region: 13CO contour levels are from 2.66 to 7.10 in steps of 0.89 K km s-1. b) For the S156 region: 13CO contour levels are from 2.53 to 6.76 in steps of 0.84 K km s-1. c) For the DR17/L906 region: 13CO contour levels are from 2.64 to 7.05 in steps of 0.88 K km s-1. d) For the M17/M18 region: 13CO contour levels are from 7.83 to 20.89 in steps of 2.61 K km s-1. |

Fig. A.4
Position-velocity diagrams of 13CO for a) MON R2, b) S156, c) DR17/L906, and d) M17/M18. The positions for 13CO are the same as in Fig. 2. a) For the MON R2 region: contour levels are 0.5 to 3 in steps of 0.5 K. b) For the S156 region: contour levels are 0.6 to 2.1 in steps of 0.3 K. c) For the DR17/L906 region: contour levels are 0.3 to 1.8 in steps of 0.3 K. d) For the M17/M18 region: contour levels are 0.8 to 3.8 in steps of 0.5 K. |

Fig. A.5
Location of the radio continuum emission (gray scale) overlaid on the H2CO observation lines (black contour lines) and H110α emission lines (dash contour lines) toward a) MON R2, b) S156, c) DR17/L906, and d) M17/M18. H2CO contour levels are the same as Fig. 1 for four regions. For the DR17/L906 region: H110α contour levels are 0.67, 0.89, 1.11, 1.33, 1.56, and 1.78 K km s-1; for the M17/M18 region: H110α contour levels are 2.91, 4.36, 5.81, 7.26, 8.72, 10.17, and 11.62 K km s-1. The gray bars are given in units of K. |
