1. A method of measuring a parameter comprising using a suitably programmed computer to perform steps including:

  • predicting a value of each of two independent measurements of the parameter for two independent measurement channels, making two independent measurements of the parameter via said two independent measurement channels to produce two measured values of the parameter, calculating respective differences between the predicted values and the measured values for each of said two independent measurement channels, combining the two measured values with weights which vary inversely with said respective differences to produce a combined value, and outputting the combined value to a user.
