1. A method for generating a sampling scheme for a device manufacturing process, the method comprising:
obtaining a measurement data time series of a plurality of processed substrates;
transforming, by a hardware computer system, the measurement data time series to obtain frequency domain data;
determining, using the frequency domain data, a temporal sampling scheme;
determining an error offset introduced by the temporal sampling scheme on the basis of measurements on substrates performed according to the temporal sampling scheme; and
determining an improved temporal sampling scheme to compensate the error offset.
