    You are doing corrections out of order probably. Try just overlapping the Sun, apply refraction as if it were a star, divide by 2. This will be your Ho to compare to Hc. I take it that you are using your GPS position as an assumed position. If not then intercepts will be large and not an indicator of precision.
