Abstract
A method including measuring a value of a directly measureable processing parameter of a patterning process from a portion of a substrate produced by the patterning process; obtaining a relationship between the directly measureable processing parameter and a not directly measureable processing parameter; and determining a value of the not directly measureable processing parameter from the value of the directly measureable processing parameter and the relationship.
