1. A non-transitory computer program product comprising machine readable instructions stored therein, the instructions, when executed by a computer system, configured to cause the computer system to at least:
obtain measurement data comprising measurement values corresponding to different modes of measurement of a sensor system configured to sample on one or more marks on a physical product unit that has been subjected to a semiconductor manufacturing process;
identify one or more components indicative of deformation of the one or more marks based on a result of a multivariate analysis applied to the measurement data or to previous measurement data; and
use the measurement data and the identified one or more components to determine a preferred mode of measurement for the sensor system based on a reduced impact of the deformation of the one or more marks on the accuracy of a measurement value obtained by the sensor system.
