Gallery of ¹²CO 6–5 spectra from ten different locations. Spectra of the IRAS 4A and 4B central positions are shown in Fig. 2. The arrows indicate the exact locations of the corresponding spectra with respect to the outflow lobes and each spectrum is given with the offset from IRAS 4A. Note the mix of narrow (<2 km s^-1) and medium (10–15 km s^-1) profiles together with the broad lines (25–30 km s^-1) at the outflowing positions close to the center of IRAS 4A. We also note that the velocity scale of the (44″, 67″) panel is different to emphasize the weak “bullet” emission (see text). The vertical scale is for T_mb. The contours are ¹²CO 6–5 emission where the levels start from 3σ (15 K km s^-1) with an increasing step size of 2σ (10 K km s^-1). The blue and red velocity ranges are selected from −20 to 2.7 and from 10.5 km s^-1 to 30 km s^-1, respectively.
