Fig. 2


CO J = 3 → 2 spectra centered on the peaks of the high-velocity lobes of area B (see Fig. 1). Vertical scale is in units of corrected main beam brightness temperature, and map offsets are given in the upper-right corner of each spectrum. Dotted vertical lines mark the outer ( − 30, 48 km s-1) and inner (0, 18 km s-1) bounds over which we integrated the high-velocity blue-shifted and red-shifted emission; solid line marks the ambient cloud velocity (VLSR = 8.8 km s-1 ). In the lower two panels, high-velocity gas forms continuus, fading-off wings, whereas in the upper two panels high-velocity gas exhibits a semi-detached distribution with a secondary peak.
