Integrated intensity ( K km s^-1) maps of the three isotopologues observed. For the C¹⁸O (left) and ¹³CO (middle), the integration range was 1 to 5.5 km s^-1. The ¹²CO (right) was integrated from −5 to 15 km s^-1. Here we can see that the C¹⁸O follows the shape as seen in extinction (Fig. 1), while the ¹³CO emission starts to pick up the outflowing material, best seen in the ¹²CO emission dominated by high velocity gas.
