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.
