Notes. aThe column density of CH3CN, which is degenerated with source size. bThe full width half maximum derived from line fitting. *Parameter fixed. cThe source size is derived from the line fitting analysis. A value of 0.0 indicates that the beam filling factor is equal to 1, meaning the source fully fills the beam. †means the components K=0-4 of CH3CN are optically thick.
