Molecular lines observed in comet 46P/Wirtanen between 11.9 and 18.1 Dec 2018 in the 2 mm band, except for HC₃ N and OCS, for which we show the weighted average of five lines expected in the 1 mm band. For some complex organics, we averaged several lines between 147 and 170 GHz (2 mm wavelength). The vertical scale is the main beam brightness temperatureand the horizontal scale is the Doppler velocity in the comet rest frame.
