The aim of this adjustment is to obtain a camera Scan-Width of:
COUGAR 25, CHAMELEON 25: 635 mm
COUGAR 36, CHAMELEON 36, PREMIER 36: 516 mm
CHROMA Tx 40, CRYSTAL Tx 40: 344.4/350.2/344.4 mm
MAGNUM XL 54: 350.9/358.9/358.9/350.9 mm
COUGAR Tx 36, CHAMELEON Tx 36, PREMIER Tx 36: 466.7 mm
The Scan-Width is correct if the total sum of Scan-Width Units (SWU) at the start and at the
end of the scanline is as shown in the table below (
1 SWU is either 1 Black Line or 1 White
Space of the Scan-Width Pattern (A )).
