Sean,
Would you please explain to me the formula you use for Refraction and where you got the figures? The 7.32 and 4.32...I don't understand them or are they the same figures used always in the formula? What does "H" stand for?
Refraction = -0.0167°/tan(H+7.32/(H+4.32)) = -1.7'
Can I use the following formula instead?
0.96/Tan(Ha)
Thanks for the help.
Sam
