Fig. 1 left panel：integral intensity (Unit in K km s-1) for CO(1-0), velocity range from -4 to -20 km/s；right panel: line noise (Unit in K) per channel for CO(1-0). 
Fig. 2 left panel：integral intensity for 13CO(1-0), velocity range from -4 to -20 km/s；right panel: line noise per channel for 13CO(1-0).  (image or by WU Yuan Wei) Fig. 3 left panel：integral intensity for C18O(1-0), velocity range from -4 to -20 km/s；right panel: line noise per channel for C18O(1-0).   
(image or by WU Yuan Wei) Fig.4: Top, middle and bellows are Spectra map for 12CO(1-0)、13CO(1-0) and C18O(1-0). 
 
(image or by WU Yuan Wei) Fig.5 Top, middle and below are rms distributions for 12CO(1-0)、13CO(1-0) and C18O(1-0). The reason for the double peak profile is that rms in the bottom region of NGC2264 are larger than the middle and top region. |
