Peter, you wrote: "Neat trick!" Thanks. Glad you tried it out. You wrote: "For refraction I took the formula from the Nautical Almanac at the standard conditions " Do you mean the formula from the back of the almanac that gives the refraction as R=0.0167/tan(H+7.31/(H+4.4))? That probably explains the slight differences between my numbers and what you found. -FER --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
