| - | The observations were obtained in the course of the line survey Green Bank Telescope Observations of TMC-1: Hunting for Aromatic Molecules. The data were recorded with very high resolution which resolves, at least in part, the complex velocity structure . No individual lines were detected, as usually in this survey. Stacking of all lines of all four major velocity components, however, yielded a signal slighly above 5σ. Note, however, that this method becomes questionable with weak lines as those of indene. As can be seen in Fig. 4 of the previous paper, TMC-1 is not line poor anymore at 1 cm wavelength on the level of the indene lines; the situation **may** be slightly better at longer wavelengths. | + | The observations were obtained in the course of the line survey Green Bank Telescope Observations of TMC-1: Hunting for Aromatic Molecules.
