Claim 13:
14. A computer program product comprising a non-transitory computer-readable medium having instructions therein, the instructions, when executed, configured to cause a computer system to at least:
obtain measurement data of a substrate;
obtain a plurality of fingerprint components from historic measurement data comprising values of a parameter measured at a plurality of positions on from previous substrates similar to the substrate;
determine a linear combination of the fingerprint components that fits the measurement data best;
reconstruct a fingerprint of the parameter across associated with the substrate based on the determined linear combination; and
based on the reconstructed fingerprint associated with the substrate information, output electronic data for configuration or modification of an industrial process or of a measurement process of substrates subjected to the industrial process.
