It gives the Earth Jupiter distance, elongation angle, and Io Phase and Longitude. 1-4 = -0.25 -0.25 ? perhaps not random ? 1-5 = -0.62 -0.62 ? perhaps not random ? 2-4 = -0.06 -0.73 3-4 = 0.04 -0.03 ? rounding difference, same algorithm ? 1-6 = 1.461 1.517 My Friend Divyadarshan does not like "Old man Victor" so: Septuagenarian Victor Dr. Victor Herrero Ph.D. M.S.
