Relationship between CH₃OH and H₂O fractional abundances (X) towards three nearby low-mass star-forming regions. The triangles represent the gas and ice fractional abundances relative to H₂ for the Coronet cluster members listed in Table 3 for which both gas and ice measurements are available. The squares and circles symbolise the values obtained for Serpens SVS 4 and Orion B35A from Perotti et al. (2020, 2021), respectively. The CH₃OH gas abundances are compared to the H₂O (panel a) and CH₃OH (panel b) ice abundances. Upper limits are marked as empty arrows. The grey line in panel a represents the linear fit to the detections. In panel b three different groups are identified, excluding Serpens SVS 4–12; they correspond to the three star-forming regions and they are marked with coloured ovals.
