Fig. 3
Average of the two individual and flux calibrated spectra of comet P/2019 LD2 (ATLAS) obtained with the 10.4 m GTC (upper panel). The spectrum of the Sun was used to obtain the continuum shown in red that was then used to remove the dust reflected spectrum and obtain the emission spectrum (bottom panel). No CN emission band was detected at the 3σ level.
