The Z1(X,Y) table and the Z2(X,Y) table are known.
The value of z1 and the value of z2 are known.
The value of x and the value of y corresponding to (z1, z2) are expected to be known.
There could be many groups of (x, y) meeting Z1(x,y) == z1 or Z2(x,y) == z2. But there should be an exclusive group of (x,y) meeting Z1(x,y) == z1 and Z2(x,y) == z2.
