Refering the data send Noticing identical values for the wet and dry results for the U.S. Standard Atmosphere at the horizon is suspicious. A check revealed that the humidity did not enter the iterative procedure to calculate the values at the horizon. It does not really change much. Just for the sake to have every thing right, here the correct values: U.S. Standard Atmosphere (wet) Values at horizon: Refraction in arc min 35.18 (changed slightly) Alitude (dip) in arc deg -0.0921 (unchanged) Dip-factor 1.747 (unchanged) K-factor 5.681 (changed slightly) I think that's it now.
