Figure 1: Channel maps of the CO(2-1) line. The contour levels are  -3, 3, 5, 7, and , where corresponds to 5.2 mJy beam-1 (=0.96 K). The cross in each map indicates the position of the 8.4 GHz radio continuum peak position of RA  and Dec  (Hagiwara et al. 2001; Bradley et al. 2004). The RA and Dec offsets are the offsets from the phase tracking center of RA  and Dec  . The synthesized beam is shown at the bottom-left corner of the first channel map.

Figure 2: Integrated intensity (moment 0) and intensity weighted velocity (moment 1) maps of the CO(2-1) and CO(1-0) lines. The synthesized beams are shown at the bottom-left corner of each image. The crosses and the reference positions of the RA and Dec offsets are the same as in Fig. 1. a) The CO(2-1) moment 0 image. The contour levels are (1, 3, 5, 7, 9, and 11) 0.334 Jy beam-1 km s-1 (=62.0 K km s-1). b) The CO(1-0) moment 0 image. The contour levels are (1, 3, 5, and 7) 0.257 Jy beam-1 km s-1 (=50.6 K km s-1). c) The CO(2-1) moment 1 image. d) The CO(1-0) moment 1 image.

Figure 3: Position-velocity (PV) diagrams of the CO(2-1) line. The contour levels are 3, 5, 7, and , where corresponds to 5.2 mJy beam-1 (=0.96 K). a) PV diagram along the north-south elongated S1 feature (PA of the cut is ). The positions for S1a and S1b are shown with labels. b) PV diagram along RA with the cut through the S1a, C, and S2 features (PA of the cut is ). The positions for S1a, S2, and C are shown with labels.
