I should add that, if memory serves (it has been a while ago that I wrote the program), the blue and green points are what an SWR 1.0:1 is transformed to by the KAT3.  

An antenna that will produce a match is actually the complex conjugate of one of the blue or green points (easy to figure out on the Smith Chart).
