Abstract: A method for determining an input to a lens model to determine a setpoint for manipulation of a lens of a lithographic apparatus when addressing at least one of a plurality of fields of a substrate, the method including: receiving parameter data for the at least one field, the parameter data relating to one or more parameters of the substrate within the at least one field, the one or more parameters being at least partially sensitive to manipulation of the lens as part of an exposure performed by the lithographic apparatus; receiving lens model data relating to the lens; and determining the input based on the parameter data and on the lens model data.
