Calibration Period
The period (usually the year) when all of the above cost input data apply, if costs are specified as spot values. Results for other years are then calculated using the relevant Cost Trends, which are normalised to 1.0 in the Calibration Period. See 10.3.7 Cost Trends and Age Factors.
Use Global Trends
If this input is set to No, any global Cost Trends are ignored for this Resource. This makes it possible to completely decouple cost assumptions for certain Resources, while retaining global trends for the remainder.
