Maximum and minimum value should not be adjacent to each other.
X (MAX.) = Maximum distance between vertical lines from X1 to Xm.
X (MIN.) = Minimum distance between vertical lines from X1 to Xm,
Y (MAX,) = Maximum distance between horizontal lines from Y1 to Yn.
Y (MIN.) = Minimum distance between horizontal lines from Y1 to Yn.

1) Terrestrial magnetism without horizontal field
(O Gauss). With vertical field of 0.2 Gauss.
2) At room temperature
3) Input signal: Crosshatch R, G, B mixed colors.
