A method and system are presented for evaluating a variation of a parameter of a pattern. The method includes processing data indicative of an aerial intensity image of at least a portion of a patterned article, and determining values of a certain functional of the aerial image intensity for predetermined regions within the at least portion of the patterned article. The values of the aerial image intensity functional are indicative of a variation of at least one parameter of the pattern within the at least portion of the patterned article or are indicative of a variation of at least one parameter of a pattern manufactured by utilizing the patterned article. |
