D/H ratios for CH2DOH (left panel) and CH3OD (right panel) across the star-forming sequence. The spread per source type was calculated using all column densities listed in Table A. The black circle denotes the average of the values. The values of CH2DOH have been statistically corrected. Violin plots demonstrate the density distribution of the data: the wider the area of the violin, the more data points are around this value; narrow regions show that data are sparse at this value. -- astro-ph.GA

The isotopic ratios of deuterated methanol derived around protostars are commonly used to infer the physical conditions under which they formed in the earlier prestellar stage.
