Notes. All spectral parameters were retrieved from the CDMS database4 (Müller et al. 2016), which report data from Pearson et al. (2008) for ethanol, Widicus Weaver et al. (2005) for glycolaldehyde and Xu et al. (2008) for methanol. (a)The latter is imaged to show the outflow morphology (see Sect. 4.1 and Fig. 1).
