I also need that to determine the error. I calculated the anomalous effect from my paper and the acceleration was on the order of 10^-26. Apparently too weak and in the wrong direction, or a mistaken calculation. > You might be interested in a thread in physics forums called "solar > system motions" (http://www.physicsforums.com/showthread.php?t=383916) > where I discuss the subject with some members.
