D/H ratio as measured in all the mono-deuterated molecules detected in the hot corino of IRAS 16293-2422 B, including the respective statistical corrections (Appendix C). This is a subset of the data points shown in Fig. 3. The data points are blue if the molecules are O-bearing and have no more than 6 atoms, fuchsia if the molecules are O-bearing and contain more than 6 atoms, green if the molecules are N-bearing, and gold if the molecules are S-bearing.
