The results shall be calculated in the order described in Table A7/1. All applicable results in the column ‘Output’ shall be recorded. The column ‘Process’ describes the paragraphs to be used for calculation or contains additional calculations.
For the purpose of this table, the following nomenclature within the equations and results is used:
ccomplete applicable cycle;
pevery applicable cycle phase;
