*2: Internall trigger mode, single operation
*3: 25 kVp (Mo target X-ray source), without filter
*4: Spatial frequency at CTF=5 %
*5: A defect line is a horizontal or vertical line containing 4 or more pixels that produce less than 1/8 of the average output from
surrounding pixels and are formed continuously from the opposite side of a horizontal shift register or a vertical shift register.
*6: Average of all active pixels in single operation at Sf (int)
Note: X-ray energy range is less than 18 keV.
