considered phase j, s;

                     n is the number of time steps in the considered phase;

                     j is the index number for the considered WLTC phase.

              3.13. Delta in CO2 emissions of period j expressed in g/s is then calculated following the equation:

                     ∆CO2,j = kv,2 x ( - )

                     where:

                     ∆CO2,j  is the delta in CO2 emissions of period j expressed, g/s;

                     kv,2  is the slope of the Veline equation-2, g CO2/kWs;

                      is the average target power of the considered period j calculated using POVERRUN,2, kW;

                      is the average actual/measured power of the considered period j calculated using POVERRUN,2, kW;

                     j  is the considered period j and it can be the cycle phase or the total cycle.

              3.14. The final distance and speed corrected CO2 emissions of period j is calculated following the equation:

                      = (∆CO2,j x /

                     where:

                      is distance and speed corrected CO2 emissions of period j, g/km;

                      is CO2 emissions of period j according to step k in Table A7/1 in Annex B7, g/km;

                     ∆CO2,j is the delta in CO2 emissions of period j expressed, g/s;

                      is the duration of considered period j, s;

                      is the actually driven distance of the considered phase j, km;

                      is the target distance of the considered period j, km;

                     j is the considered period j, which can either be the cycle phase "p" or the total cycle "c";

                     k is "1" if the considered period j is the cycle phase, or "2" if the considered period j is the total cycle.
