I have a question about land observations (NOT using natural horizon, say art horizon, or distances). My altitude over the sea level is 530 m. This should somehow affect refraction (decrease the magnitude of the correction?). How much? Can I rely on the almanac refraction tables in my observations? They are surely made for the sea level. I have an unexplained error of the order of 0.3' in many of my observations. Can my altitude be responsible for this? Alex.
