NOTE:
The above data is measured with spot light source.
The spot size is 1 mm in diameter, and the wavelength is 565 nm.
The light is operated in pulse mode so that light intensity of 4,000 pho-
toelectrons is obtained.
The light source is scanned with 1 mm step on the photocathode, the
output signal is calculated and plotted in accordance with the position
of the light source.
The fluctuation of the position signal is 0.3 mm at FWHM.
