Appendix A: Additional figures

thumbnail Fig. A.1

Continuum maps at 23.7 GHz for IC 342 (left), Maffei 2 (middle), and NGC 253 (right). The contour levels are, −0.3, 0.3, 0.6, 1.2, 2.4, 4.8 mJy beam-1 for IC 342, −0.6, 0.6, 1.2, 2.4, 4.8 mJy beam-1 for Maffei 2, and −2.7, 2.7, 5.4, 10.8, 21.6, 43.2, 86.4 mJy beam-1 for NGC 253. The beams are shown at the bottom left corner of each map.

Channel maps of the NH3(1, 1) and NH3(2, 2) transition emission from IC 342. The contour levels are −0.9, 0.9, 1.8, 2.7, and 3.6 mJy beam-1 and −0.75, 0.75, 1.5, 2.25, and 3 mJy beam-1, respectively. The synthesized beams are shown in the lower left corner of the first panel for each transition. The gray scale images represent the continuum emission at 23.7 GHz.

Channel maps of the NH3(1, 1) and NH3(2, 2) emission from Maffei 2. The contour levels are −0.78, 0.78, 1.56, 2.34, and 3.12 mJy beam-1 and −1.2, 1.2, 2.4, 3.6, and 4.8 mJy beam-1, respectively. The gray scale images show the continuum emission at 23.7 GHz. Beams are shown in the left upper panel for each map set.
