10 Comparative spectra of Epsilon Eridani: on the left hand the data acquired with the SPECTRA-2 backend show a clear detection with a SNR > 4; on the right hand, the same target was simultaneoulsy acquired with the old spectrometer MSPEC0 used for the Jupiter – Comet impact Both spectra were obtained by means of a similar instrumental and antenna setup. Please note that MSPEC0 was not able to detect any visible feature.

11 Spectrum of the exoplanetary target Lalande observed at a frequency of 22 GHz, with the Noto INAF-IRA radiotelescope.

12 Gliese 581, Noto, 30-08-2012. Boxcar filter
