The horizontal axis in each panel represents time in days from 0.01 to 360, followed by steady state. The vertical axis represents power per unit length in watts per metre from 0 to 250. Circles mark real values, and crosses mark predicted values. In the twenty-fifth percentile error panel, power decreases from about 210 watts per metre at 0.01 days to about 30 watts per metre at steady state. Predicted values remain slightly below the real values at most times. In the fiftieth percentile error panel, power falls from about 190 watts per metre at 0.01 days to about 34 watts per metre at steady state, with predicted values generally below the real values. In the seventy-fifth percentile error panel, power declines from about 120 watts per metre at 0.01 days to about 33 watts per metre at steady state. The predicted value is above the real value at 0.01 days, while later predictions are close to or slightly below the real values.Real vs predicted power output for samples at the 25th, 50th and 75th percentiles of the mean absolute error (MAE)
