¹³CO intensity maps, integrated for two velocity intervals, of the molecular cloud associated with NGC 2264 cluster (see Ridge et al. 2003). The bulk of the molecular cloud has V_LSR between 4 km s^-1 and 6 km s^-1, and a clear separate component is present at 10–11 km s^-1 corresponding to the Fox Fur Nebula (compare with Fig. 5). The contours are the same for both panels, starting at 1.5 K km s^-1 with increments of 1.5 K km s^-1.
