All odorants used, the first 10 are the fixed odorants and the remaining are rotators, columns as follows: odorant number; 2-letter odorant code; odorant common name; odorant CAS number; odorant dilution volume-by-volume in IPM before encapsulation; compound identification number (CID) identification number; the number of subjects that rated the odorant; the average odorant intensity rating. Note that odorants KO and HG are the same molecular species, KO supplied by Sigma-Aldrich and HG by DreamAir. The mixtures are equal combinations of their components without added dilution. We printed 13 booklet types, each containing the 10 fixed odorants and 2 of the rotators. The 13 rotator pairs were: “KO+JT”; “UV+OS”; NB+OA”; “TJ+EK”; “IF+AS”; “HG+BA”; “SS+WZ”; “LB+RZ”; “FM+VY”; “MH+SF”; “ZI+WV”; “FE+UB”; “NE+WV”. We printed 800 copies of each type but the last, (“NE+WV”) of which we printed 400.
