Notes.

(1)

Quantum numbers are - JKa,Kc.

(a)

Observed frequency of the transition assuming a LSR velocity of 5.83 km s−1. See text for the laboratory data used for initial frequency predictions of each molecular species. For lines for which only upper limits are given, their frequencies correspond to the predictions obtained from a fit to the laboratory plus space lines (see Table B.1).

(b)

Integrated line intensity in mK km s−1.

(c)

Linewidth at half intensity derived by fitting a Gaussian function to the observed line profile (in km s−1).

(d)

Antenna temperature in milli Kelvin.

(A)

Upper limit corresponds to 3σ.

(B)

The line is partially blended but still possible to derive line parameters.

(C)

This line is blended with an U line. Line width has been fixed.

(D)

This line is blended with a feature stronger than expected. It is, more likely, an unknown line.

(E)

This line is blended with a transition of H2C4N.

(F)

This line is heavily blended a transition of C13CCCCH. Line parameters can not be derived.

(G)

The frequency of this transition of CH2CCHC4H is within a poor sensitivity zone of the receiver.

(H)

This line is blended with a broad 1 mK unknown line.

(I)

A 3σ feature do appears just at the expected frequency of this transition.
