The centre of mass and integrated intensity of the input data as a function of the correlation between experimental and simulated pulse train statistics. (a) The distribution of the recorded centre-of-mass locations of pulse intensities observed experimentally. High correlation denotes recorded pulse intensities for which the geometric phase approximation of our model is suitable. Clustering of the centre of mass corresponding to simulated pulse trains with intensity statistics that are highly correlated (ρ > 0.95) and uncorrelated (ρ < 0.25) to those observed experimentally indicates the success and failure conditions of the model. (b) A comparison of the mean experimental intensity distribution used as input to the phenomenological model for these success and failure cases, illustrating that poor correlation arises from input data where significant truncation of the pulse intensity occurs.
