Millimetre lines observed with IRAM 30-m in comet 67P in 2015. Left panel: HCN(3–2) line at 265886.434 MHz with the position and relative intensity of the hyperfine component shown from the average of 18.25 to 20.40 September 2015. Right panel: Sum of the four CH3OH lines at 303366.893, 304208.324, 305473.472, and 307165.911 MHz observed on 22.30 September 2015. 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.
