Comet C/2012 F6 (Lemmon): average on-nucleus spectrum of the HCN (32) line at 265.886 GHz obtained with the IRAM 30 m telescope between 14 March and 8 April 2013. Spectra covering the same velocity range obtained at similar times for H13CN (32) (259.012 GHz) and HC15N (32) (258.157 GHz) are also shown for comparison, but do not show a clear detection. Vertical scale is main beam brightness temperature and horizontal scale Doppler velocity in the comet rest frame.
