A substantially rectangular spectral representation is synthesized, which is adapted to produce image capture device sensor outputs if applied to an image capture device. In one aspect, a method of improving retention of superabrasive particles held in a solidified organic material layer of an abrading tool, a portion of each of said superabrasive particles protruding out of the solidified organic material layer is provided. An imaging error affects circuit structures and further measurement marks in the same way. Each transaction code is cancelled when the transaction is terminated. The asset may be stored with the re-encoded loudness setting.
