* Where a range of ODPs is indicated, the highest value in that range
shall be used for the purposes of the Protocol. The ODPs listed as a
single value have been determined from calculations based on laboratory
measurements. Those listed as a range are based on estimates and are
less certain. The range pertains to an isomeric group. The upper value
is the estimate of the ODP of the isomer with the highest ODP, and the
lower value is the estimate of the ODP of the isomer with the lowest
ODP.
** Identifies the most commercially viable substances with ODP values
listed against them to be used for the purposes of the Protocol.
