A method for compensating perturbed measurements comprises: obtaining measurements with respect to time of a signal representing a parameter modified by a perturbing influence and a signal representing the perturbing influence and storing the measurements for each time in a data array as parameter data and perturbation data respectively; for each of the parameter data and the perturbation data: fitting a mathematical model to the data with respect to time; determining an error between the model and the data at each time; storing the errors in the data array as normalised parameter data and normalised perturbation data respectively; fitting a mathematical model to the normalised parameter data against the normalised perturbation data to obtain a correlation function representing correlation between the parameter data and the perturbation data; using the correlation function to calculate a correction factor representing the modification of the parameter data by the perturbing influence; using the correction factor to adjust the parameter data for the modification to obtained compensated parameter data; and outputting the compensated parameter data. |
