There is no dip correction ("height of eye") when an artificial horizon is used. First you apply the index correction and then you divide the result by 2 to get Ha. After that the procedure is the same as with a natural horizon; i.e. apply corrections for refraction, parallax, and semidiameter to obtain Ho.

George,
My understanding is no. The artificial horizon is the horizon for your shot. Substract out height of eye and apply refraction and any other corrections you may have and that is it.
