Millimetre lines observed with IRAM 30-m in comet 67P on 12–16 November 2021. The vertical axis is the main beam brightness temperature in kelvins, and the horizontal axis is the Doppler velocity in the rest frame of the comet with respect to the main line. For methanol, we have chosen to show, at high spectral resolution, the sum of the three strongest lines observed around 165 GHz with the VESPA correlator.
