^aOdorant ID corresponds to identifiers shown in Figure 5. All odorants were diluted in mineral oil to theoretically emit a vapor-phase partial pressure of 3 Pa (Cleland et al., 2002); the resulting percentage volume/volume concentrations are listed. Odor sets 9–13 consisted of binary mixtures of two odorants, as listed.
