-At DBT=95 and Speed=2, this performance map would yield CapRat=1.00 and COP=5.58.  At other (DBT,Speed) combinations, suitable 2D interpolation is performed on each lookup variable.  Lookup variables are extrapolated outside of PMGRIDAXIS ranges; adequate axis ranges must be provided to avoid unrealistic extrapolation.
