Schematic illustrating the new approach described here for computing the k-space information for chemotactic trajectories using experimental probability distributions. In this approach, the probability distribution is established using the Fourier coefficients from a number of chemotactic trajectories collected under some reference condition. These distributions (the EPDs), for the real and imaginary parts of the coefficients, are used in place of the PPD to compute a kSI_E. Note that the EPDs shown are schematic, but they do not have a simple analytical shape
