Notes. The PdBI images have been convolved to the same angular resolution (5.9″× 5.9″).

^(*)

The k = 0,1,2 and 3 components are blended. The velocity of the Gaussian fit is calculated relative to the frequency of the k = 0 component, ν = 91 987 MHz.

^(a)

The ~326 km s^-1 component of H₂CO overlaps with the ~270 km s^-1 component of HC₃N.

^(b)

A possible ~180 km s^-1 component of H₂CO would overlap with the ~93 km s^-1 component of HC₃N.
