The elevation angle appears to be between 30.4 degrees (where the power is maximum, i.e., 316 kW) and 39.4 degrees (where the power is minimum, i.e., 262 kW). Power variations are therefore small, unlike those shown in Figure 15 which fluctuate between 150 kW and 400 kW during the power phase, with an average of 92 kW over the entire cycle.
