Appendix A: H2CO line parameters

Table A.1

Line parameters.

Appendix B:

B.1. H2CO spectral lines

thumbnail Fig. B.1

Spectra of different positions marked by the numbers in Fig. 2. All transitions from a given position are presented in the same panel but with different offsets along the y-axis on a scale. The Gaussian fits are indicated with green lines, and the central velocities of the components are shown as dashed vertical lines.

B.2. Velocity channel maps

thumbnail Fig. B.2

Channel maps of the H2CO 303 − 202 emission. Black contour levels for the molecular line emission (on a scale) are from 0.16 K (2σ) in s.pdf of 0.16 K. Velocity channels range from −27 to +81 km s-1in s.pdf of 2 km s-1. The central velocities of the channel maps are shown at the top of each panel. The wedge at the side shows the intensity scale of the line emission. The beam size of 30″ is shown in the bottom-left corner.
