Top, middle, and bottom panels show the CO (2–1), CO (1–0) and ﹩^{13}﹩CO emission, respectively, from EU And. The low‐resolution spectra have been obtained with the 1 MHz channels filter bank, whereas the high‐resolution spectra have been obtained with the autocorrelator and smoothed to the same velocity resolution of 0.2 km s﹩^{-1}﹩. The narrow spike at +5 km s﹩^{-1}﹩ in the CO (1–0) spectrum is interstellar.
