Notes: The default unit of measure (UoM) shown in the "Recommended Input Units" column is the UoM value that OR assumes if no UoM is included in the parameter statement.

Make sure that the various parameters are inserted into the correct locations in the INCLUDE file. See the previous page for guidance.
