Hello Larry
I just got it... I was making some wrong assumptions within the example about the absolute angle between objects when there is index error.
I worked it out graphically and came to the realization that if ic is added to hs then THAT number represents twice the altitude of the body.
So now I fully comprehend the math - add index error to AH and divide by 2.... or half each and add together. Works the same either way.
This whole exercise was well worth the effort. It's nice to be able to bounce ideas off like minded folks.
Thanks
Cheers.
