Parameter of scanning
・ Angle Allowance : tan θ<= 0.4
・ Ph cutlens side : 8 ( tan θ< 0.1 ) , 7 ( 0.1 =<
tan θ )stage side : 7 ( tan θ< 0.1 ) , 6 ( 0.1 =<
tan θ )Parameter of Ph cut depends on thickness of emulsion at scanning
Thickness of Lens side is more thin than stage side about 5 micron

conclusion
・ data taking speed is 10 days / both surface / 25 cm2 / brick with 1 shift / 18h / day @ 33 cm2 /h
-> 40 days / both surface / 100 cm2 / brick
・ dead space of scanning data is less than 1% depends on emulsion itself
