Hanning-smoothed spectra from positions centred at selected globulettes; green: ¹²CO(2–1); black: ¹²CO(3–2); blue: ¹³CO(2–1); red: ¹³CO(3–2). The signals related to the globulettes are marked. Corresponding spectra of CN 38, 78 and 80 are shown in Figs. 4 and 5. Strong emission from shells and/or background components are present in the panels of CN 79, 93, 119, 93-Frag, and objects E and F.
