CONTENTS

First AWB detector area I-PLUS

NOTE :

First AWB detector area I-MINUS

First AWB detector area Q-PLUS

Data to set first area should be larger than

data to set second area.

First AWB detector area Q-MINUS

Second AWB detector area I-PLUS

Second AWB detector area I-MINUS

Second AWB detector area Q-PLUS

Second area should be closer to the cross

point of I-axis and Q-axis, compared to first

area.
